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
