Question

A pendulum takes 40 seconds to complete 20 such motions. Calculate the time period of the pendulum. Name the factor on which the time period of a pendulum depends on
​

Answer 1

Explanation:

Total number of oscillations = 20

Time taken = 40 seconds

Therefore,

Time period of the pendulum

= Time taken/Total number of oscillations

= 40/20 = 2 seconds

The time-period of a pendulum depends on the length of the pendulum. Greater it's length, greater will the time-period and vice-versa
