Gravitation

Gravitational Potential

a) The work done in bringing a unit mass form infinity to a point in the gravitational field is called the 'gravitational potential' at that point.
b) Gravitational potential at a point P distance r form a point mass 'M' will beV = -

c) Unit of Gravitational potential is Joule/kg
d) Dimensional formula of Gravitational potential is [M0 L2 T-2].
e) Gravitational potential is a scalar quantity.
f) At r = ∞, V = 0.
