Two small plastic spheres each have a mass of 2 grams and a charge of -50 nc. they are placed 2 cm apart (center to center). a) what is the magnitude of the electric force on each sphere? b) if one sphere is held in place what is the resulting acceleration magnitude of the other?

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
