A satellite of mass 
is revolving in a stable circular orbit at a height 
above the Earth's surface, where 
is the radius of the Earth. What is the minimum amount of additional energy required to make this satellite escape from Earth's gravitational pull? (Let 
be the acceleration due to gravity on the Earth's surface, and 
be the mass of the Earth.)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
The satellite is at a height 
above the Earth's surface, so its distance from the Earth's center is
.
The gravitational potential energy
.
The kinetic energy
