A 42-kg girl walks to the top of stairs that are 3.0-m high. How much gravitational potential energy does the girl gain?

P.E = 1234.8Joules

Explanation:

Given the following data;

Mass = 42kg

Distance = 3m

We know that acceleration due to gravity is equal to 9.8

To find the gravitational potential energy

P.E = mgh

P.E = 42*9.8*3

P.E = 1234.8Joules

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.
