  1. Sir 31:09 par apne neeche wale block ka acc nikala h 1 m/s^2 par sar woh to tab ayga na jab ham neeche wale ground ki friction assume na krre is case m to sir ground se bhi friction a raha to uske according to sir jitna upper wala block agaeforce laga rha h 10 kg wale par utna hi ground peeche lgarha h to block rest par hona chahiye n?

  2. Sir in the last problem why did u take normal reaction 10 instead of taking 35 bcoz it should be (m1+m2)g but u took only 5 kg block instead of 10kg and 5 kg both..

  3. sir ek question ha jab apne 28:57 m f max 15 likha vo galat h kyunki phle jo humne assume kiya tha frictionless less plane m kiya tha jisme sirf ek frictional force thi but jab idr f limit aage lgage block b par tab usko oppose bhi to krege ground friction so how can fmax remains same explain…

  4. Sir at 7:38 aapne kaha ki M1 pe horizontal surface normal reaction lagayega Jo (m1+m2)g hoga par sir kya m2 bhi m1 par ek normal reaction nahi lagayega aapne pichle videos me bataya tha….Please sir clear my doubt…..And sir awesome explanation skills…aap hi to hai Jo aaj ki date me education ko business ki terms me nahi le rahe ..Thank you sir

  5. Sir #31.20 pe jo aapne 10 kg ka block ka fbd bnaya hai usme ek hi force sirf aage ki taraf q likya hi ek or friction force surface or 10 kg k block k bich hoga naa? Qki aapne aapne niche wale block or surface k beech v friction coff.. 0.1 liya hai naa ki zero… Fir to resultant force kuch or aayega and accln.. Kuch or pls #reply
