A simple pendulum makes 50 oscillations in one minute. What is its period of oscillation?

Answer Details

The period of a pendulum is the time it takes for one complete oscillation, which is the time it takes for the pendulum to swing back and forth once.
In this question, we are given that the simple pendulum makes 50 oscillations in one minute. To find the period of oscillation, we need to divide the total time taken by the number of oscillations.
We can convert one minute to seconds by multiplying it by 60, since there are 60 seconds in one minute.
So, the time taken for 50 oscillations is:
Time = 1 minute/50 oscillations = 60 seconds/50 oscillations = 1.2 seconds/oscillation
Therefore, the period of oscillation of the pendulum is 1.2 seconds.
Therefore, the correct option is (d) 1.20s.
