I have a q. in bth cases,5N also applies a downward normal force on 10kg right? we just ignore it bc its in vertical equi?

[@zero0bb]

​@@samairamalik3404No, gravitational force acts downwards. To understand normal force imagine you are pushing a wall, the force you give while pushing a wall is defined, we can call it F(human) signifying a human is giving a pushing force. But, the wall will not move, why? because of a multitude of factors and forces, there are too many to take into account but we know that the normal force always manages to equate the force we give on the wall. That is what normal force is, when a rigid body is immovable a normal force is said to act opposite to it. Hope i helped

most welcome dear keep learning

[@aspirant_IIT-KGP]

Note for my future reference - First step, second step for friction ques uk We have 2 categories Jaha F neeche Wale par lage Jaha F upar Wale par lage For no. 1 F max corresponds to f limiting for upar wala Final step me F = m sys (a max) [that chotu upar wala box can tolerate) When F exceeds F max neeche wala aur upar wale ka FBD alg-alg banake solve Karo! Ese me koi confusion hoga hi ni! Ki neeche Wale box ki final Force ea me m sys hoga ki m box etc etc For no. 2 F max corresponds to f limiting of lower box Here don't u dare forget ki f static is self adjusting so acc to values in ques they can ask F min and F max both!.. F max corresponds to f limiting F min corresponds to f kinetic (for lower box) Baki all well!..😁👍

At 20:14 what if I applies a force of 27N f1m(maximum static friction is 25N) therefore making fbd for the case we get 2N as the net forward driving force with acc=0.4 m/s² But that same 25N (frictional force) would be acting on 10kg block also and the resisting force there equals 15N and hence as a result 10N is the net force.. therefore acceleration should be 1m/s² Then sir how can the range be 15 to 30N.. correct me if I am wrong anywhere
