## Homework Statement

A simple pendulum consists of a small object of mass 2.4 kg hanging at the end of a 2.0 m long light string that is connected to a pivot point.

(a) Calculate the magnitude of the torque (due to the force of gravity) about this pivot point when the string makes a 3.0° angle with the vertical.

(b) Does the torque increase or decrease as the angle increase?

(c)Explain your answer.

## Homework Equations

A=Lsinө

τ=Amgsinө

## The Attempt at a Solution

a. A=2.0m sin 3.0

A= 0.105m

τ=0.105m (2.4kg)(9.8m/s

^{2})sin 3.0

**τ= 0.129 Nm**

b. angle will increase

c. Since angle increases, sin of the angle also increases
