Question

Study the following statements and find which is/are true.

I. The motion of pendulum with the effect of dissipative force is known as damped oscillation.

II. Swinging of a child in a swing (without external push) is the example of free oscillation.

Choose correct option

(a) I only

(b) II only

(c) I and II

(d) All are wrong

Answer 1

Answer is : (a) I only

In damped oscillations the motion of simple pendulum die out gradually due to air drag and friction of the support. The oscillation of a child swinging in a swing cannot be sustained due to resistive forces present in nature.
