Question

10). A simple pendulum completes 30
oscillation in one minute. Find it's
frequency. *
O 0.67 Hz
O 1 Hz
O 0.50 Hz
O None of these

Answer 1

Answer:

0•50

Explanation:

Oscillation in one minute = 30

Its frequency = 30/60 = ½

½=0•5

Answer 2

Given:

• The number of frequencies = 30
• Time = 1 min = 60 secs

To Find:

• The frequency of the simple pendulum.

Solution:

Frequency is defined as the number of oscillations per second

Therefore, the formula to find the frequency of a simple pendulum is given by

f = N/t → {equation 1}

Where "N" is the number of oscillations and "t" is the time

On substituting the values in equation 1 we get,

⇒ f = 30/60 {dividing the etrms}

⇒ f = 0.5 Hz

∴ The frequency of the simple pendulum = 0.5 Hz (option 3)
