Question #45036

Consider two plastic spheres, 1 meter apart: a little sphere with a mass of 1 kg and an electric charge of +1 nC, and a big sphere with a mass of 11 kg and an electric charge of +11 μC. Find the electric force and the gravitational force between these spheres. Which force is stronger? (k0 = 9 x 10^9 N-m^2/C^2, G = 6.7 x 10^-11 N-m^2/kg^2)
