Question

A bob of a metre pendulum swings through 10
cm arc in a given time interval. Find its angular
displacement in the given time interval.​

Answer 1

Answer:

The angular displacement of the pendulum in the given time interval is 0.1 radians

Explanation:

Length of the arc = 10 cm

length of the string of the pendulum = 1 metre = 100 cm

Anglular displacement of the pendulum is given by

$\theta=\frac{\text{Arc Length}}{\text{String Length}}$

$\implies \theta=\frac{10}{100} =0.1 \text{ radian}$

Thereofore, the angular displacement of the pendulum is 0.1 radians

Hope this answer is helpful.
