The Attempt at a Solution
I think : the question means that almost all of the potential energy gets used into the explosion.
If this is true then the potential energy gets reduced by ## \frac { GM^2} R ## or if the star just gets transformed into a bigger sphere, then its final potential energy will be ## \frac { GM^2} R_f ## , where ## R_f ## depends on the final density. Since the final density is unknown, I can solve the question this way.
So, the correct opinion is (e).
Is this correct?
