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

A

`15m//s^(2)`

B

`3m//s^(2)`

C

`10m//s^(2)`

D

`5m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Mass `(m)=0.3 kg rArr F= m.a=-15x`
`a=-(15)/(0.3) x=(-150)/(3)x=-50 x`
`a=-50xx0.2=10 m//s^(2)`
