Please, can someone help me with this?
A neutron star and a black hole are 2.400e+12 m from each other at a certain point in their orbit. The neutron star has a mass of 2.78×1030 kg and the black hole has a mass of 9.94×1030 kg. What is the magnitude of the gravitational attraction between the two?

drwls,
Use the same Newtonian formula that you would use for any other pair if masses, M1 and M2.
F = G*M1*M2/R^2
G is the universal constant of gravity, 6.67*10^11 N*m^2/kg^2
F is the force
