Two blocks $A$ and $B$ of masses $3\,m$ and $m$ respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of $A$ and $B$ immediately after the string is cut, are respectively

A$g,g$

B$\frac{g}{3},\frac{g}{3}$

C$\;g,\frac{g}{3}$

D$\;\frac{g}{3},g$

Two blocks $1$ and $2$ of equal mass $m$ are connected by an ideal string (see figure below) over a frictionless pulley. The blocks are attached to the ground by springs having spring constants $k_1$ and $k_2$ such that $k_1 > k_2$. Initially, both springs are unstretched. Block $1$ is slowly pulled down a distance $x$ and released. Just after the release the possible values of the magnitudes of the accelerations of the blocks $a_1$ and $a_2$ can be
