Answer 1

100J is the answer hope this can help

Answer 2

The gravitational potential energy of the object is 100 J.

Gravitational potential energy stored in an object is the work done in raising the object to a height h against the gravitational force acting on it.

The gravitational force acting on a body is its weight mg, where m is its mass and g, the acceleration due to gravity.

Work done by a force is equal to the product of the force and the displacement made by the point of application of the force.

`GPE = mgh`

The weight of the object is given as 20 J and it is raised to a height of 5 m.

`GPE =(mg)*h = (20 N)*(5m)=100 J`

The gravitational potential energy of the object is 100 J.
