A simple pendulum takes 20 seconds to complete 10 oscillations.
What is the time period of the pendulum?
The time period (T) of a simple pendulum is defined as the time taken by it to complete one oscillation.
The pendulum completes 10 oscillations in 20 seconds, so the time taken to complete one oscillation would be
T = Total time/ Total Oscillations = 20 seconds/10 oscillations = 2 seconds for 1 oscillation.
