Four 7.5 kg spheres are located at the corners of a square of side 0.50 m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.
so i tried to use the equation Fg = Gm1m2/r^2. So i did Fg = (6.67X10^-11)(7.5)(7.5)/.5^2 and got 1.50075 X 10^-8. but i got it wrong. i just learned about this equation so i was wandering if i'm using it right? can anyone help me on how to start the problem?
