Gravitational Potential Energy - L2

Physics

definition

Gravitational Potential (V)

The gravitational potential (V) is the gravitational potential energy (U) per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.

definition

Gravitational Potential due to a point mass

Gravitational Potential due to a point mass is given by:

example

Field due to different arrangements of shells

Example: Two concentric shells of masses and are having radii and . Find the expression of gravitational field in different regions of shells.

Solution:
A uniform shell has no contribution to the gravitational field inside it from Gauss Law for Gravitation. Using this principle,
gravitational field would be 0 for
gravitational field would be  for 
gravitational field would be  for
