Question

Force on particle, of mass ‘m’, undergoing SHM is given by: F = -kx. What is the relation between x and angular frequency w?

(a) k = w^2w

(b) k = m√w

(c) m = k/w^2

(d) m = k^2/w

I have been asked this question in an interview for job.

The question is from Oscillations in chapter Oscillations of Physics – Class 11

Answer 1

Right choice is (c) m = k/w^2

The best explanation: The force on a particle in SHM = -mw^2x(t).

Given that: F = -kx(t). We get:

k = mw^2

Or m = k/w^2.
