Question

All surfaces are frictionless and the pulleys and the string are light. A block of mass $2 \, \text{kg}$ rests on an incline of $30^\circ$ ; a light string attached to it passes over a pulley fixed at the top of the incline, runs down under a movable pulley that carries a block of mass $4 \, \text{kg}$ , and its far end is tied to the ceiling. The acceleration of the block of mass $2 \, \text{kg}$ is:

A
$g$
B
$\frac{g}{3}$
C
$\frac{g}{2}$
