An oscillating mass spring system has mechanical energy `1` joule, when it has an amplitude `0.1m` and maximum speed of `1ms^(-1)`. The force constant of the spring is (in `Nm^(-1))`

A

`100 N//m`

B

`200 N//m`

C

`300 N//m`

D

`50 N//m`

Text Solution

Verified by Experts

The correct Answer is:
B
`T.E_(max)=(1)/(2)KA^(2)`
`1=(1)/(2)xxKxx0.01`
`therefore K=(2)/(0.01)=200N//m`
