A particle oscillating under a force `vecF=-kvecx-bvecv` is a (k and b are constants)

A

simple harmonic oscillator

B

linear oscillator

C

damped osillator

D

forced oscillator

Text Solution

Verified by Experts

The correct Answer is:
C

A particle oscillating under a force `vecF=-kvecx-bvecv` is damped oscillator. The first term `-kvecx` represents the restoring force and second term `-bvecv` represents the damping force.
