Problem set 2 (Chapter 22) 1. Four identical positive charges +q are placed at the corners if a square of side L. Determine the magnitude and direction of the electric field due to the four charges at the point P midway of the side of the square. 2. Two very large parallel metal plates separated by a small distance d are given opposite uniform charges, creating a uniform electric field E in the space between then plates. An electron is projected with an initial velocity v 0 through a small hole in the positive plate. It travels halfway across the gap between the plates before stopping and reversing direction. Find E in terms of the initial velocity v 0 , the mass of the electron me and d, and e, the magnitude of the electron’s charge. 3. Charge Q is distributed uniformly along the x axis from – L to + L. Determine the electric field at the point P (0, a) 4. Three thin plastic rods, each of length 2L, carry charges Q, Q and –Q respectively, distributed uniformly on each rod. The rods are arranged to form an equilateral triangle. Determine the electric
