Two spheres A and B of mass 6.0 kg and 7.3 kg respectively are separated by a distance of 0.65 m.

(a) Calculate the magnitude of the gravitational force A exerts on B and B exerts on A.

2 answers

both the same ( Newton #3 action equal and opposite to reaction)

F = G * 6 * 7.3 / .65^2

where G = 6.67 * 10^-11
6.9 x 10 ^-9
