The potential energy as a function of displacement for an oscillator `u=8x^(2)` joule. The magnitude of the force on the oscillator of mass 0.5 kg placed at x = 0.2 m is

A

1.6 N

B

3.2 N

C

0.8 N

D

4.8 N

Text Solution

Verified by Experts

The correct Answer is:
B
`u=8x^(2)`
`PE=8x^(2)`
`(1)/(2)kx^(2)=8x^(2) therefore k=16`
`F=(1)/(2)kx=(1)/(2)xx16xx0.2=1.6N`
