Q. In the arrangement shown, the pulleys and the strings are ideal. The acceleration of block $B$ is

$g /5$

$g /2$

$2 g /5$

$2 g /3$

For $B : m g - T = ma$

For $A : 2 T - m g = \frac{ma}{2}$

$\Rightarrow m g = \frac{5}{2} ma$

$a = \frac{2 g}{5}$

Q. In the arrangement shown, the pulleys and the strings are ideal. The acceleration of block B is

g/5

g/2

2g/5

2g/3
