Question

A sinple pendulum makes 10 oscillations in 20 seconds.What is the time period and frequency of its oscillations

Answer 1

Time period of the pendulum will be the time taken by it complete one oscillation .

Hence,

Time period = 20/10= 2 seconds

Frequency is the reciprocal of th time period of the body.

So,

Frequency = 1/time period = 1/2 = 0.5 hz
