Question

a satellite of mass 100kg perform uniform circular motion around earth at height 6400km from earth surface. Find its gravitational potential energy​

Answer 1

640000

Explanation:

multiply 100 into 6400

Answer 2

Gravitational Potential energy of the satellite is 6272000 joules.

Explanation:

Given data

Mass of the satellite = 100 Kg

Height at which the satellite is located from the earth = 6400 km

Find the Gravitational Potential energy of the satellite

• The potential energy of an object present in a gravitational field is called as Gravitational Potential Energy.
• This find application in satellites revolving around the earth surface.
• For the satellites, the lift force is based on its weight and they are equal also.
• Hence, the Gravitational Potential Energy is equal to the product of  the weight of the satellite and the height at which it revolves.

Gravitational Potential energy = Weight × height    

Weight = mass (m) × gravity (g)

Gravitational Potential energy = mass (m) × gravity (g) × height    (Joules)

Gravitational Potential energy = m × g × h  (Joules)

Substitute the respective values in above equation, where g = 9.8 (m/s²)

Gravitational Potential energy = 100 × 9.8 × 6400    (Joules)

Gravitational Potential energy =  6272000  (Joules)

Therefore the Gravitational Potential energy of the satellite is 6272000 Joules.
