A satellite is orbiting close to the earth and has a kinetic energy K. The minimum extra
kinetic energy required by it to just overcome the gravitation pull of the earth is
A
B
K
C
D
2K
Text Solution
Verified by ExpertsThe correct answer is:
B
: Kinetic energy 
Potential energy 
Total energy 
To overcome gravitational pull, total energy will have to be zero.
So required extra K.E.
