Question

An object of mass 10kg is raised to height of 200m above the ground then its potential energy at its height will be

Answer 1

Answer:

20 KJ

Explanation:

Given :

• Mass of the object = 10 kg

• Height to which the object was raised = 200 metres

To find :

• Potential energy of the object

Potential energy = mass×gravitational force × height

Potential energy = 10×10×200

Potential energy = 100×200

Potential energy = 20,000 joules

1000 joules = 1 kilojoule

Potential energy = 20 KJ

The potential energy of thw object is equal to 20 KJ
