A simple pendulum completes 20 oscillations in 40 seconds. What is its time period?
Options
Option A is correct
2 seconds
Option B
0.5 seconds
Option C
20 seconds
Option D
40 seconds
Explanation
The time period of a simple pendulum is the time taken to complete one oscillation. It is calculated by dividing the total time taken by the number of oscillations. Here, Time Period = Total Time / Number of Oscillations = 40 seconds / 20 = 2 seconds. Option B is incorrect as it's the reciprocal. Options C and D are simply the number of oscillations and total time, respectively, not the time period.
