Two large asteroids start with an initial separation of r0, at which time they each exert a gravitational force on the other of strength F0.  After they have fallen toward each other for a period of time, their separation has decreased to 0.38r0.  At that moment, what is the strength of the new gravitational force that each asteroid feels, in terms of F0?    Blank 1. Calculate the answer by read surrounding text.  times F0.   Express your final answer to at least 3 significant figures.
