to jump, you exert 1400N of force on the ground. (it exerts 1400N back on you) you applied this force over a distance of 0.3 m as your extend your legs. how much work have you done? how high will you ride into the air if your mass is 70 kg?

(there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
