Two large conducting parallel disks, each with charge +/- 36.0 µC and diameter 0.280 m are separated by 2.4 m. A particle with a mass of 54 g and charge 5.3 nC is shot from the lower negative disk with an initial velocity of 2.34 m/s toward the upper positive disk. What distance from the negative plate will the particle reach? [0.168 m]

47. Charge Q is uniformly distributed along a thin, flexible rod of length L. The rod is then bent into the semicircle shown in FIGURE P23.47. a. Find an expression for the electric field E at the center of the semicircle. Hint: A small piece of arc length ?s spans a small angle ?? = ?s/R, where R is the radius. b. Evaluate the field strength if L = 10 cm and Q = 30 nC.
