Energy stored in the spring will be
Explanation:
We have given spring constant of the spring K = 5 dyne/cm
We know that
And 1 cm = 0.01 m
So
It is given that spring elongated from 20 cm to 22 cm
So change in length of the spring x = 22 - 20 = 2 cm
As 1 cm = 0.01 m
So 2 cm = 0.02 m
Now energy stored in the spring will be equal to
So
So energy stored in the spring will be
