Correct option is C)

Mass of A is m

If mass A move to a distance x, then spring will stretch to x value. And it will lift the mass of B

Force in the spring, F=kx=Mg ...... (1)

Kinetic energy = Potential energy

2 1 ​ kx 2 =mgx kx=2mg...... (2) From (1) and (2) Mg=2mg m= 2 M ​

Required mass of A is

2 M ​ , to lift mass B

The correct Answer is C

Solution

The spring will exert maximum force when the ball is at its lowest position. If the ball has descended through a distance x to reach the position,

`mgx=(1//2)Kx^2` or `x=2mg//K` (i)

For the block B to leave contact spring force,

`Kx=Mg` (ii)

Comparing Eqs. (i) and (ii), `m=M//2`
