Two springs have their force constant as...

Two springs have their force constant as `k_(1)` and `k_(2) (k_(1) gt k_(2))`. When they are streched by the same force.

A

No work is done in case of both the springs

B

No work is done in case of both the springs

C

No work is done in case of both the springs

D

More work is done in case of first spring

Text Solution

Verified by Experts

The correct Answer is:
C
`W=(F^(2))/(2k)`
If both springs are stretched by same force then `W prop(1)/(k)`
As `k_(1)gt k_(2)` therefore `W_(1)lt W_(2)`
i.e. more work is done in case of second spring.
