Gravitational Potential
Gravitational potential at surface of Earth (mass M radius R) is:
Select the correct option:
Solution
-GM/R
Gravitational Potential (V) at a point is the work done per unit mass in bringing a test mass from infinity to that point. V=−∫∞Rg⋅dr=−RGM
- Potential is always negative because the gravitational force is attractive.
- It is a scalar quantity. The value is zero at infinity and decreases as you approach the mass.
