Homework Statement
Question: Four 8.0 kg spheres are located at the corners of a square of side 0.50m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.
Answer from Back of Textbook: 3.3 x10^-8 N toward diagonally opposite sphere
Homework Equations
F = (Gm1m2)/r^2
m1 = mass1
m2 = mass2
G = constant 6.67 x 10^-11
r = radius
g = (Gm)/r^2
g = acceleration due to gravity.
I believe that these are the only two applicable to this question.
The Attempt at a Solution
Er, its kinda hard to attempt it if you don't have a clue what's going on. If someone could just push me in the right direction and give me a hint as to where to start, that would be awesome!
