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?

  1. 4.22Kg
  2. 4.22 g
  3. 385Kg
  4. 8550g

hintHint:

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 cross times45
    = 8550g
