Acceleration Gravity Earths Surface Potential Energy Object Raised Surface Height Radius

If g is the acceleration due to gravity at the Earth’s surface, the gain of the potential energy of an object of … (b) mgR/2 (c)…

Answers:

Correct option  MgR/2

  Explanation:

Let the potential energy of an object at earth’s surface be U1

where,

  M = mass of earth 

 m = mass of object 

 R = radius of earth

Potential energy of the object at a height, h = R from the surface of the Earth.
