gravitational force of stars

A neutron star and a black hole are 3.40e+12 m from each other at a certain point in their orbit. The neutron star has a mass of 2.781030 kg and the black hole has a mass of 9.941030 kg. What is the magnitude of the gravitational attraction between the two?

F= GM1M2/R^2

F=6.674 10−11 (2.78x 1030)(9.94x1030)/(3.42+12)^2
