Two springs have their force constants `k_(1)` and `k_(2) (k_(2) gt k_(1)`) . When they are stretched by the same force _____ .

A

No work is done in case of both the springs

B

Equal work is done in case of both the springs

C

More work is done in case of fist spring

D

More work is done in case of second spring

Text Solution

Verified by Experts

The correct Answer is:
D
Work done = Energy stored
`= (1)/(2) kx^(2)`
For second spring x will be more, whose square is involved in above expression.
