One is never too late. There are more than +800 pyqs solved in detail. Watch them properly and you will find the difference in your paper solving skills. Keep sharing!
dm is used for small mass and x is different quantity that is distance from center. You can integrate dm/x^2. That is why x^2 is is taken with dx and then integration is done on both the sides.
try again q no 3 [ 4 FIRST MASS calculate then maximum ke lia differentiation =0 KARTE H ] [5 W APNE AXIS per rotation ka angular velocity hoti h for earth 🌎 🌎 T =24 hours ] [ 10 momentum conservation lagana tha and if velocity i s less than orvital velocity h to elleptical path hoga ]

So it was a big mistake that I underrated this chapter since I studied it appropriately but didn't practice such tough questions. Thanks for bringing them to us in an organised manner. 💗
In that one integration based question where it was asked to find potential at a distance x from the origin on the x axis provided gravitational force as a function of x, I integrated with right method but did mistake by taking lower limit as 0 instead of infinity. This shows how careful you have to be at every step while solving a physics problem. Coming back to give feedback, three to four questions were really good especially that one in which we have to conserve momentum in both the axes. Got to learn a lot from the session, it was really great explanation from your side sir!
2020 ke questions itne time consuming isliye thay kyonki inka weightage kam tha abb to ek session mein 21-22 sawaal aate hai like jan ,april June , July

I am feeling so bad that I found your channel so late... Your explanation skills are 🔥🔥🔥🔥🔥🔥🔥🔥
Thanks Bhaiya
One is never too late. There are more than +800 pyqs solved in detail. Watch them properly and you will find the difference in your paper solving skills. Keep sharing!
And welcome to Eduniti Family.
@@mohitgoenka99 Yes bhaiya... Thank u so so much..
At 12:00 sir hamne mass dm/x^2 ko sath mein integrate kyu nahi kiya? Please bataiye.
dm is used for small mass and x is different quantity that is distance from center. You can integrate dm/x^2.
That is why x^2 is is taken with dx and then integration is done on both the sides.
Done your 2021 playlist now doing 2020 then rbs
Thank you for such a god level content
🙏
excellent dear
try again q no 3 [ 4 FIRST MASS calculate then maximum ke lia differentiation =0 KARTE H ] [5 W APNE AXIS per rotation ka angular velocity hoti h for earth 🌎 🌎 T =24 hours ] [ 10 momentum conservation lagana tha and if velocity i s less than orvital velocity h to elleptical path hoga ]
well done dear
keep learning and solving
32:34 me thoda doubt hai sir v1 velocity √gm/r na hoga..... orbital velocity wahi ma hota hai
Orbital velocity √Gm/r hota hai but jab rocket eject karega to uski orbital radius 2R hai , 2R per vo circular orbit me ghum raha hai

Sir please tell me which pentab u used plz reply sir
Sir aap itne focused or itna serious kaise rehte ho 😅
will try to be more smiling in coming videos dear
Sir gravitation done 2days mei ab next chapter kinematics
Proceeding in 45 days checklist
So it was a big mistake that I underrated this chapter since I studied it appropriately but didn't practice such tough questions. Thanks for bringing them to us in an organised manner. 💗
Sir in 1st questions we should use g= GMx/R^3
Since we are taking g at surface its okay to use either equation. even if you use GMx/R^3 and put x = R, it becomes GM/R^2. I hope its clear now.
@@mohitgoenka99 got it sir .... thank you
In that one integration based question where it was asked to find potential at a distance x from the origin on the x axis provided gravitational force as a function of x, I integrated with right method but did mistake by taking lower limit as 0 instead of infinity. This shows how careful you have to be at every step while solving a physics problem.
Coming back to give feedback, three to four questions were really good especially that one in which we have to conserve momentum in both the axes. Got to learn a lot from the session, it was really great explanation from your side sir!

Revise : Question 3 ,4 ,11 , 12 , 16
5th Question ka calculation time taking hoga so instead, gh-ge =~0.03m/s^2 leke minute mein answer laa sakthe hain.
yes

the level of questions are just insane but until you are here , there's nothing to fear
Started 30 days checklist on (1.5x), first 2020 bcz sir said its quite harder .😁😁

Us
2020 ke questions itne time consuming isliye thay kyonki inka weightage kam tha abb to ek session mein 21-22 sawaal aate hai like jan ,april June , July
48:00 Q15 doesn't give any slightest idea for first the point where field is zero.
Have to think yourself.
well done dear
#learnlikeneverbefore
quality to length ratio is very high of this channel thats why i love it
Thnx dear
conclusion: conservation of momentum and angular momentum ka kahan kahan use hoga uspe focus krna h mujhe
