Question

The force acting on a particle of mass 1kg is -2x, where x is the displacement from the mean position of SHM. What is the time period of oscillations?

(a) 2π s

(b) π√2 s

(c) π s

(d) 2√2π s

The question was asked in quiz.

I'd like to ask this question from Oscillations in portion Oscillations of Physics – Class 11

Answer 1

The correct option is (b) π√2 s

For explanation: Using k = mw^2,

we get: 2 = 1w^2

or w = √2.

Thus, time period = 2π/w = π√2 s.
