Question

The minimum acceleration that must be imparted to the cart in the given figure. So that the
block A will not fall (given u = 0.5 is the coefficient of friction between the surfaces of block
and cart) is given by
​

Answer 1

Answer:

When a cart moves with some acceleration toward right, then a pseudo force

acts on block toward left. This force

is action force by a block on cart. Now, block will remain static w.r.t. cart, if frictional force
