Consider the figure shown here of a moving cart C. if the coefficient of friction between the block A and the cart is `mu`, then calculate the minimum acceleration a of the cart C so that the block A does not fall.

Text Solution

Verified by Experts

The forces acting on the block A (in block A's frame
(i.e. non inertial frame) are:
For A to be at rest in block A's frame i.e. no fall,
We require `W=f_(s)rArrmg=mu(ma)` Thus `a=(g)/(mu)`
