1- Two charges of equal magnitude opposite in sign, +Q and -Q, separated by a distance 2a are located at points (-a,0) and (a,0) on the x-axis. Find the electric potential at the origin. How much work is needed to separate these charges infinitely away from one another? Answer: Vo = 0, W = Q/2a 2- A charged particle (q = -8.0 mC) is released from rest at point A. At point B the kinetic energy of the particle is equal to 4.8 J. What is the electric potential difference VB – VA? Answer: 600 V. 3- Two point charges, q1 = +3x10° C and q2 = -2x10° C are separated by a distance d = 6 m. Find the electric potential (V) at the mid-point between qı and q2. Answer: 3 V.
