33:00 min In that math if we assume a surface at (h=R) height from earth surface then the total distance between two R'=R+R=2R and we can apply Ve=√2GM/R' =√2GM/2R =√GM/R =7.9 km/s Is that process right?

Sir, In centre of mass chapter,"Impulse,Variable Mass System and Rocket Propulsion" are still pending.So,can you please make videos on these missed topics as soon as possible,Sir??
sir jo 59:00 pe question krare usme to ham logic se bhi kr skte , jiska mass jyda uski escape velocity highest, options me Vr already highest di thi, then all have same density and Q has more area so it has more mass than P , so by that 2nd option , and if Q is greater than Vp/Vq will be 1/2....
I read NCERT with all my heart and never noticed these kinds of points.Morelike I couldn't come up with these conclusions.Of course,I got someone of them my own but all others were only cleared because of you sir, Thank you sir /dhanyavaadh aapka.

In that math if we assume a surface at (h=R) height from earth surface then the total distance between two R'=R+R=2R and we can apply Ve=√2GM/R'
=√2GM/2R
=√GM/R
=7.9 km/s

Osm!!! U learn difficult things in easy manner
1,2,3 energy is -ve
4 energy is 0 zero
5 energy is +ve.
At 30.00 , this question could be directly done by ' √2gr ' and r=2R
Same answer 7.9
Did the same thing and got the answer, was starting to wonder if I was wrong since nobody seemed to mention it
Sir in the last question , we can actually attempt the question by second method which will hardly take 1 min
As we know in escape velocity =√2gR
Now as we know ; area of P = A
; Area of Q = 4A
As wel know Area = 4πR²
This implies that escape velocity is directly proportional to R² then simple we can find the ratio of escape velocity of P to Q which comes out 1:2 (so option c)
Now this implies VQ > VP
Which lead us to the option one n only (b)

43:20 I think for the calculation of potential energy by the sun the distance should be r+2R as the object is at the other end (diameter of earth)
r already includes the radius of earth and the other radius of earth makes it (r+Radius of earth)
you are the best, sir.
Your videos make my concepts strong.
thank you sir for everything
One like for sir for solving 2012,2015 and 2017 adv. Questions.
Thanks a lot .
Sir, In centre of mass chapter,"Impulse,Variable Mass System and Rocket Propulsion" are still pending.So,can you please make videos on these missed topics as soon as possible,Sir??
ok
Yes yes its required.....
thik hai kal dal dunga
Laws of motions mai hai
sir jo 59:00 pe question krare usme to ham logic se bhi kr skte , jiska mass jyda uski escape velocity highest, options me Vr already highest di thi, then all have same density and Q has more area so it has more mass than P , so by that 2nd option , and if Q is greater than Vp/Vq will be 1/2....
The best teacher ever ❤
0:45 😂😂 oh ho matching t-shirt!!!
You understand students heart, love you sir ❤❤
thnku sir
u hv removed my fear pschology from physics.
i promise one of the best ranks in neet-2019 's gonna come from my side.
thnku again
How was the neet paper???
Kon se rank aai apki
how many marks???
Kon si rank ayi, 😂😂🤣🤣. Ho gaya na dabba gol.
I read NCERT with all my heart and never noticed these kinds of points.Morelike I couldn't come up with these conclusions.Of course,I got someone of them my own but all others were only cleared because of you sir, Thank you sir /dhanyavaadh aapka.
Nice explanation sir thanku for this wonderful explanation
Agr body ki velocity Kam ho orbital velocity se, to body revolve to nhi kregi... Or revolve nhi kregi to elliptical path bhi follow nhi hoga.. blke 1 parabolic path follow Hoga...
@ 05:10 ..
Sir aapke t- shirt waala formula me whole root nahi hai
Bhai notice kiya
Hum bhi same formula par rehe hai abhi
Yarrr tm log bas galtiyaan dhhond paana itna khtrknaak awsm content h wo bhale na dikha ho tm log ko ajeeb ho yr
Sir mai apki sabhi video dekti hu ❤ mujhe apki purani video 📷 bahut pasand hai ❤😊mai bsc 1st semester mai hu aur aap se physics padh rhi all concepts makhan 😊
sir aap "Mitar" de mt bola kijia
ir sounds...like this👉😥😌
btw vey nice lecture😄😄😄😄😃😃😃😃
mere to scl ke teacher 1 hour me pura ka pura gravitation ka chapter hi
complete kra dia 😂😂😂😂😂😂(escape velocity se v jada speed hoti h ye scl ke teachers ki)😋😋😋😂😂
i wish ki main aapka kisi trh se kuchh me v help kr pau jaise aap hm logo ki study me help kr rhe ho🙏🙏salute you and many many love to you😘😘
😀😀😀
Suna hai aapne air2 laya hai neet 2020 me🤔
🙂🙃🙃🙂🙂
1:06:00 it’s also becoz there no magnetic field (no protection from solar winds ) on moon , so whenever solar storm comes it takes the gas particles present of moon’s surface with it
Vy toh gravitational attraction Kam hoke magnetic field hone se bhe gas rahe lega Kya moon pe? Not calling you out, just asking.
ZTS really appreciate your hard work sir.... speacially your extra sound effects, 😂😂
Congratulations 🎉🎉 sir
5 million subscription has completed on this plateform.
It shows that alakh sir is heart beat of millions of student's 🤗🤗.
N thank you so mch sir.. For everything.... You'll always be... My roll model 🙏🙏.
You give me new definition of ... Education, new definition of life.
Sir you have proved that what is the hard work,,... What is the struggle... .
What is the consistency.... What's the dedication.
This all reasons make you a inspiration for.. All students, person.
Again..
Thank you soo much sir.. From heart. 😊
Thank you sir ❤️
01.escape Velocity at H height?
02. Escape velocity between 2 planets
03. Earth, sun and একাধিক potential energy
04. G/4 hoy, when it is projected at "V"
Hey, where are you from?
Sir boht hi sahi tha last question Maja aah Gaya👍👍👍
Sir you are great 👍
Sir we are are very thanks to your studying pattern and style for us😎😎
Sir your best in teaching nobody here like you
sach me hi pyara h physicswallah
Best teacher in my life
Last MCQ was awesome nailed it
56:07
Goosebump Feeling🤯
Sir ab or kitni videos baki h for gravitation😅💚
1 mai hi complete hojayga poora chap 50 se 55 minute ki video mai khatam hojaygi
3 videos aur h
Sir kabhi reply nhi krte
3
r +R ko kaise r le liye sir R ki bhi value chhoti nahi hoti
sir last wala question me toh mene density compare karke bata diya ki konse options sahi h
