Question

The following diagram shows that a simple pendulum consisting of a bob of mass 100 gram. Initially the bob of pendulum is at rest at 'O' it is then displaced to one side at 'A'. The height of 'A' above 'O' is 5 cm (take g=10m/sec²)

Answer 1

Answer:

We should find potential energy.

Explanation:

Given: mass 100g.

g=10m/s^2

Height = 5cm at A.

So, PE At A is 0.1×10×5= 5J.
