A block of mass 2kg is connected to a vertical spring constant `800N//m` as shown. At `t=0`, the spring is relaxed. Now the block is released. List-I givens time t and List-II gives the comments on the velocity and the position of block at that time.

Text Solution

Verified by Experts

The correct Answer is:
B
`T=2pisqrt(m/k)=2pisqrt(2/800)=(pi)/10`
