A particle of mass 0.6kg is subjected to a force of F= -kx with k= 15 `Nm^(-1).` What will be its initial acceleration if it is released from a point 20 cm away from the origin ?

A

`5 m//s^(2)`

B

`10 m//s^(2)`

C

`3 m//s^(2)`

D

`15 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`m = 0.3 kg, F=-kx`
Force (F) `=15 xx 0.2 = 3N`
`a = F/m = 3/0.3=10 m//s^(2)`
