Solution

The correct option is B $\frac{m}{4}$
$\frac{1}{2} k {(\frac{m g}{k})}^{2} = M_{B} g (\frac{2 m g}{k}) \Rightarrow M_{B} = \frac{m}{4}$

Find the minimum of block B so that A leaves the surface when B is released from rest and spring at natural length

The correct option is B m412k(mgk)2=MBg(2mgk)⇒MB=m4

The correct option is B $\frac{m}{4}$
$\frac{1}{2} k {(\frac{m g}{k})}^{2} = M_{B} g (\frac{2 m g}{k}) \Rightarrow M_{B} = \frac{m}{4}$
