Answer 2

The shift of 3kg block is 2m towards left.

Explanation:

$x_{cm}=\frac{m_{1}x_{!}+m_{2}x_{2}}{m_{1}+m_{2}}$

$x_{cm}$-position of center of mass $x_{1}$ and $x_{2}$ are position of masses $m_{1}$ and $m_{2}$.

Δ$x_{cm}$=$m_{1}$Δ$x_{1}$+$m_{2}$Δ$x_{2}$/$m_{1}+m_{2}$

Δ$x_{1}$=$3m$

$0=\frac{2*3+3x_{2}}{2+3}$

$0=6+3x_{2}$

$3x_{2}=-6$

$x_{2}=\frac{-6}{3}$

$x_{2}=-2$

so, shift of $3kg$ block is $2m$ towards left.
