Question

20. If g is acceleration due to gravity on earth's surface, the gain in potential energy of an object of
mass m raised from surface of earth to a height equal to radius R of the earth is?​

Answer 1

Answer:

mgR

Step-by-step explanation:

Given, mass = m

Acceleration due to gravity = g

Radius = R

Potential energy = mgh Joules

= mgR Joules
