Question

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 string is cut, are respectively :

• A. $g,g/2$
• B. $g/2,g$
• C. $g,g$
• D. $g/2,g/2$

Answer 1

The correct option is B $g/2,g$

$a_A=\frac{g}{2}$

$a_B=g$
