Question

# There is a bell at the top of a tower that is 45 m high. The bell weighs 190 N. What is its gravitational potential energy?

- 4.22Kg
- 4.22 g
- 385Kg
- 8550g

Hint:

### If the bell has a weight of 190 N and 45 m high, the GPE is 8550g.

## The correct answer is: 8550g

- The gravitational potential energy GPE= mgh.
- h = 45 m

m = 190N

GPE = mgh

= 190 45

= 8550g
