From the given, choose the correct option
.

Options

A. acceleration of block `A` is zero
B. acceleration of `B` is g
C. acceleration of block A is non zero
D. tension in the string connecting A is zero

Answer

A, B, D

Explanation

If we consider free body diagram of `p_(1)` and `p_(3)` same string having tension `2T` and `T//2` this is possible only when `T` is zero. So acceleration of block A is zero and acceleration block `B` is
