1. (30 points) Short answer questions. a) (5 pts) A positive charge of value q and mass m is placed between two parallel plates. Draw the trajectory of the charge between the plates below. +Q -Q +5 b) (7 pts) A point charge is placed a distance d from a very large sheet of uniformly distributed charge (assume it is infinitely large). The point charge experiences a force F. If I move the charge to a distance d/8 from the charged plane, by what factor does the force on this particle change? is plane $E = \frac{1}{4\pi\epsilon_0} \frac{q}{r^2}$ $F_g = F_e$ $F_e = qE$ $F_e = qE$ $q = \frac{F_e}{E} = q(\frac{1}{4\pi\epsilon_0} \frac{q}{(d/8)^2})$ $q = \frac{F_e}{E} = \frac{1}{4\pi\epsilon_0} \frac{64q^2}{d}$ would increase the force by 64 +2
