A body of mass m is suspended to an ideal spring of force constant K. The expected change in the position of the body due to an additional force F acting vertically downwards is,

Options

A. `(3F)/(2K)`
B. `(2F)/(K)`
C. `(5F)/(2K)`
D. `(4F)/(K)`

Answer

B

Explanation

Let the change in the position of the body due to an additional force F is y.
`F=1/2ky`
`y=(2F)/k`
