Answer :
The painter's gravitational potential energy is 1470J
What is gravitational potential energy?
The energy that a body has or acquires when its location changes as a result of being in a gravitational field is known as gravitational potential energy. Gravitational potential energy can be defined as an energy that has a relation to gravitational force or gravity. Since the painter is on the top of a 3m platform his gravitational potential energy is given by W=mgh where m is the mass of the painter, g is the acceleration due to gravity and h is the height of the painter from the ground.
Now according to the question,
Mass of the painter=50Kg
Height of the platform=3m
Acceleration due to gravity=9.8
W=50×9.8×3
W=1470J
Therefore, the gravitational potential energy of the painter is 1470J
