Be sure to answer all parts. (a) Calculate the energy in joules of a 4.91 g object moving at a speed of 745 m/s. Ek = J

(b)

Determine how much greater the electrostatic energy is between charges of +2 and −2 than it is between charges of +1 and −1 (assume that the distance between the charges is the same in each case).
