Question

A simple pendulum takes 15sec to complete 5 oscillation. What is the time period of pendulum

Answer 1

Answer:

We know that time period=

Total time taken/Total number of oscillation

Given,

total time=15s

total no. oscillations=5

therefore

time period =15/5

= 3s.

please mark it as brainliest.

Answer 2

Time taken = 10s. No. of oscillations = 5. So,Time period of pendulum = time taken/no. of oscillation = 10s/5 = 2s. Hence, the simple pendulum takes 2seconds to complete 1 oscillation.

therefor answer is 2 seconds
