We assemble a group of three charges, each of + 2.0 µC, bringing them in from infinite distance, where we set V = 0. We put the first charge at x = 0 cm, then put the second one at x = 10 cm, and last put the third one at x = 20 cm. What was the total work done by the applied force? (Hint: At each step, W_applied = + Delta(PE) = + q Delta(V), where q is the charge you're bringing in now and V is determined by the charges that are already in place.)
An negative point charge Q = - (1.000x10^0) µC is located at the origin. An electron is initially placed at at distance (2.8000x10^-1) m from Q. The initial velocity of the electron is zero. Under the electric force, the electron accelerates and moves to its final location, (9.40x10^-1) m from Q. What is the final kinetic energy of the electron?

Two air-filled balloons each have a mass of m = 3.9 g. Each balloon hangs from the same point by its own string of length L = 0.41 m. Each balloon is rubbed to give it a static charge. Both balloons are rubbed the same amount, so each balloon has the same unknown charge (q1 = q2). The hanging balloons push away until each makes and angle of θ = 16° with respect to the vertical. Determine the magnitude of the charge, in coulombs, on either one of the balloons. Remember that each balloon has the same charge. (q1 = q2)
