1. The problem statement, all variables and given/known data
Estimate the gravitational potential energy released in the collapse of a 1.2 solar-mass core from an initial density of 10^9 g/cm^3 to a final 10^15 g/cm^3.
2. Relevant equations
3. The attempt at a solution
The book doesn't provide much guidance on this. I was thinking of using q= 3/5 assuming the density is constant. Then manipulate M^2/R to Rho*(M)*(R^2)*(4pi/3). And plug in the values for Rho that are given and substitute 1.2 for M. But theres no mention of what the radius is. Do I just use the solar-radius?
Never mind the above. I think I computed it correctly.
