Class: Electrmagnetics

As mentioned in class, the methods used in electrostatics can also be applied to Newtonian 
gravitation. Consider a spherical star of mass M and radius R. For simplicity, let’s assume 
that the density of the star can be approximated as

p = c1(1 - (r/R)),  ? ≤ ? (where r is less than or equal to R)
where c1 is a constant.
a. Determine the gravitational field produced by this star everywhere in 
terms of the mass M and radius R.
b. Use your answer from (a) to determine the gravitational self-energy in 
terms of mass M and radius R.

As mentioned in class, the methods used in electrostatics can also be applied to Newtonian
gravitation. Consider a spherical star of mass M and radius R. For simplicity, let's assume
that the density of the star can be approximated as
p = c₂ (1-7),
r≤R
