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

A

`5m//s^(2)`

B

`10m//^(2)`

C

`3m//s^(2)`

D

`15m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`F= -kx`, where `k= 15N//m and x=0.2m`
`therefore |F|= 15xx0.2=3N`
`therefore ` Acceleration `= (F)/(m) =(3)/(0.3)= 10m//s^(2)`
