Question 338503: a bull and a cow elephant, each of mass 2000kg attract each other gravitationally with a force of 1 X10-5N. Haw far apart are they? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Newton's Law of Gravitation says
F = Gm1m2 / d^2 now plug in what we knwo
5 N = (6.67 x 10^-11)(2000)(2000) / d^2 and solve for d...
Get your calculator out...
d = .0073 m or 7.3 mm apart
