The masses of blocks A and B are same and equal to m . Friction is absent everywhere. Find the mgnitude of the normal force which block B presses on wall and acclerationsof blocks A & B.

Question

Eshan · Answer

apoorv sahu · Answer

Accleration A 1 and A 2 are correct but as asked in question and as give in my answer booklet the value of normal force which block B presses on wall is N aw = 12mg/25.

apoorv sahu · Answer

Further correction in my above answer : let normal force acting on block B i.e on the lower block is N b w , then a new equation will be formed which will give the normal force of block B on the wall: N 1 =mA 1 => N 1 =12mg/25 ….....answer

Eshan · Answer

Here, it has been asked the force by wall onto the block and what we have written as ‘N’ is the normal acting between the two blocks.

The normal from the wall by looking at the FBD of M1 will be $N_w=Nsin37^{\circ}=\dfrac{4}{5}mg\times \dfrac{3}{5}=\dfrac{12}{25}mg$
