- Find the proper potential energy of gravitational interac-
tion of matter forming
(a) a thin uniform spherical layer of mass m and radius R;
(b) a uniform sphere of mass m and radius R
- Relevant Equations
- u = dm*p/2
Actually, i don't even started the solution because i am confused, i am not sure what the question is asking, i tried to see the solution, but it was using
, i don't know what that equation mean. Can you help me? P is like potential electricity, for gravitational force?
