Q. Two blocks $A$ and $B$ of masses $2m$ and $m$, respectively, are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in the figure. The magnitudes of acceleration of $A$ and $B$ , immediately after the spring is cut, are respectively

A) $g,\ g/2$
B) $g/2,\ g$
C) $g,\ g$
D) $g/2,\ g/2$
Explanation
