QUESTION
a square of edge length 15.0 cm is formed by four spheres of masses m1 = 5.10 g, m2 = 3.30 g, m3 = 0.800 g, and m4 = 5.
a square of edge length 15.0 cm is formed by four spheres of masses m1 = 5.10 g, m2 = 3.30 g, m3 = 0.800 g, and m4 = 5.10 g. In unit-vector notation, what is the net gravitational force from them on a central sphere with mass m5 = 2.00 g?
