Question

A pendulum oscillates 60 times in 40 seconds. Find its time period and frequency?​

Answer 1

Explanation:

Time period (T) of a simple pendulum means the time required by it to complete one oscillation. ⇒T=4×6040=6s. Frequency (f) of a simple pendulum is the reciprocal of its time period. Hence the time period of the pendulum is 6s and the frequency of the pendulum is 0.167Hz.

Answer 2

Explanation:

time period of a pendulum =60/40

= 3/2
