Hi! This is Mitu.
Welcome to my TH-cam Channel. Previously known as - Demystifying Physics.
I am a Physics Postgraduate. I have done B.Sc. (Hons) Physics from Gargi College, DU and M.Sc. Physics from Hansraj College, DU.
I will try to make Physics easy for students of class 9, 10 and 12. I hope my videos will clear your concepts and develop your interest in Physics.
I can assure you good quality content and will cover lots of numericals and conceptual questions for your better understanding.
🔴Physics is my main focus, but I'll also be sharing videos on math, biology, and chemistry from time to time. Subscribe to my channel for a mix of science and math content !
Lots of Love!!

Hi maam im presentlt styding in tiruppur abacus international Montessori school as im worried about upcoming board it would really help us if you create a vedio on suggesting how to write exam like dos and don't s i feel really happy if u make an exam timetable for 21 board exam
Question is wrong 😂😂😂
yes ma'am please make a series of doing important questions to be done for boards please
Sure
@PhysicsbyMitu thank you ma'am
Thank you mam ❤❤
Thank you mam
Nice explanation
But maan V°2 is smaller value than V°1 so should it be C beam
It is retarding / negative potential. When it comes to stopping potential - more negative value of stopping potential means more energy required to stop electrons For Eg : -2V means it takes less energy to stop electrons : less KE of emitted electrons -5V - it takes more energy to stop electrons - emitted electrons have greater KE and incident light has high frequency
Emitted electrons itne energetic hai ki hume zyada negative potential dena pad rha hai unhe stop karne ke liye.. revise photoelectric experiment to understand this concept
Mam can I do (i) part by M=flux/Current? Kya mam yeh galat hoga?
Vo bhi thik hai.. because straight line graph hai..
Mam why it is prop. to L²?
You mean L proportional to N2 ?? I have explained the derivation in video
Bilkul sahi hai maam mera bhi yehi answer ara hai aur google par video solution dekhra hu toh woh log zabardasti 12 answer nikal rhe kuch smjh nhi ara tha udhar se sab fraud teachers ne ratta mara hua hai zabardasti answer nikale hue hai but apki video se bohot help mili Thank you maam
Ma'am... Why can't we find an answer out of these options only? If i consider the formula e = -N(d§B/dt), so 'e' is directly proportional to d§B/dt, i.e. 'e' is directly proportional to §B. Now, § is directly proportional to B.A and since A is constant, so § is directly proportional to B. And B is highest according to option (d) nT. So among the given options, why can't (d) be the correct answer ma'am?? Please help ma'am 🙏🏻🙏🏻🙏🏻
Your logic is wrong. Hope you have understood calculation of emf in video.. apka ans put karke dekho in emf.. sin ka value zero aayga.. sin(2πnT/T)= sin(2πn)= 0 for n=1,2,3... means emf is zero according to your option
@@PhysicsbyMitu Ok ma'am, I have understood the question. I did understand your solution in the video, and now I'm also clear that why my logic was wrong. Thank you so much ma'am.🙏🏻🙏🏻
Brilliant 🦭
Ma’am my answer is also this But in book and other video it’s coming 12
I have done it correct.
Thanks Mera Bhi Yehi Aa Raha Tha Par Sab Jagah Wrong Ans diya hua hai ❤
Thank you so much mam happy looking for these explanations everywhere but only you provided me with the right amount of answers and questions thank you so much may god bless you
greatly explained🎉

very helpful!
Thank you Maam
Thanking to you mam❤🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉
Actually ma'am emf= -d(@)/dt....
i also calculated dφ/dt.. dφ/dt= d(BA)/dt

Mam continue karo video bnani future ma student ko solution ke jarurat hogi
I will be back soon. (2/3 days)
Madam neeraj sir ke pdf download
??
maam yaha pe jab emf wala graph bna rhe toh vo increasing kyu nhi banega direct upr jaake phir 2 sec baad eeche kyu aa jeyga like linear increasing banna cahiye tha na jaise flux ka bana tha
Mam please aap remaining chapters ke bhe videos bana dijiye aap bhot aacha padhaate ho mam please make maximum videos
Sure, I will resume videos in a day or two.. got unwell and then got busy with my students’ exams
