Calculate the attractive force of gravity between a 0.27 kg birthday cake and a 8 kg student who is standing 1.82 m away from it

24.  A spacecraft traveling from Earth to the Moon reaches a point where the pull of the Moon’s gravity is equal to that of the Earth’s.  Before this point the speed of the spacecraft is decreasing and after this point the speed is increasing (a little like coasting up a hill and then back down the other side).  Determine the precise location of this point. Can only use Newton's laws and uniform circular motion formulas for speed and acceleration. You can use the Fg=G(M1M2)/r^2 and g=GM/r^2)

Two spheres A and B of mass 7.0 kg and 8.3 kg respectively are separated by a distance of 0.50 m. (a) Calculate the magnitude of the gravitational force A exerts on B and B exerts on A. force A exerts on B force B exerts on A (b) If the force between the spheres is now 2.30 x 10-9 N, how far apart are their centers? m
