Question

A simple pendulum completes 60 oscillations in one minute .Find its frequency and time period.

Answer 1

Answer:

Frequency = 1 Hz

Time period = 1 sec

Answer 2

Answer:

Frequency=1 Hz

Time Period T=1Sec

Explanation:

Tip

• The oscillatory motion of a simple pendulum is defined as the periodic to and fro motion of the pendulum, with the equilibrium position as the centre of oscillation.

Given

Number of oscillation(N)=60

Time (T)=60 second

Find

Frequency=

Time Period=

Solution

$Frequency f=\frac{N}{t}=\frac{60}{60}=1 \mathrm{~Hz}$

$Time period, \mathrm{T}=\frac{1}{\mathrm{f}}=1 \mathrm{sec}$

Final Answer

Frequency=1 Hz

Time Period T=1Sec
