Question

# Find the potential energy if the body has a mass of 2 kg and is falling from 10 m.

- 190J
- 195J
- 196J
- 199J

Hint:

### Potential energy= mass x gravitational acceleration x height.

## The correct answer is: 196J

### Given,

mass of the object = 2 Kg

Height from which the object is falling = 10m

According to the formula,

Potential energy= mass x gravitational acceleration x height.

PE = 2 x 9.8 x 10 ( gravitational acceleration = 9.8m/s^{2})

PE = 196J
