Question

A simple pendulum completes 50 oscillations in one minute. Find its:
(a) frequeny
(b) time period

Answer 1

TOPIC :- SIMPLE HARMONIC MOTION AND WAVES

Subtopic :- Simple pendulum

• CONCEPT :- Time period of a simple pendulum is the taken to complete one oscillation.
• Frequency is the number of oscillation in 1 sec .

Given,

Number of oscillation in 60 sec = 50.

Hence, number of oscillation in 1 second = 50/60 = 5/6.

Therefore, freqency = 5/6 per second

Also, Time period = 1/frequency.

Hence, time period = 6/5 second
