In the above diagram system is in equilibrium if applied force `F` is doubled how much mass less block will more towards right before new equilibrium is achieved
.

A

`F/K`

B

`(2F)/K`

C

`F/(3K)`

D

`F/(9K)`

Text Solution

Verified by Experts

The correct Answer is:
D
Equivalent spring constant is 9k

Displacement is `(2F)/(9K)-F/(9K)=F/(9K)`
