The restoring force acting on a particle...

The restoring force acting on a particle executing SHM is 10 N at a displacement of 2 cm from mean position. The restoring force at a displacement of 3 cm is

A

20 N

B

15 N

C

`(20)/(3) N`

D

`(40)/(9) N`

Text Solution

Verified by Experts

The correct Answer is:
B
`(F_(2))/(F_(1))=(y_(2))/(y_(1))`
`F_(2)=F_(1)(y_(2))/(y_(1))=(10xx3)/(2)=15N`
