A particle of mass 0.3kg is subjected to a force F=kx with `k=15N//m` and x being its distance from the origin. What will be its initial acceleration if it is released from a point 20cm away from the origin.

A

`5 ms^-2`

B

`10 ms^-2`

C

`3 ms^-2`

D

`15 ms^-2`

Text Solution

Verified by Experts

The correct Answer is:

B

Force on particle at 20cm away F=kx
`F=15 times 0.2=3N `
`therefore` Acceleration =`(force)/(mass)=3/0.3=10ms^-2`
