A charged oil drop of mass m and electric charge q falling through air experiences a resistive force - myu. Starting from rest, it falls for a time interv I. At time t = 71, an oscillating electric field E Eo cos wt is turned on. (Suppose that 2 = 0 at t = 0 and is positive in the downward direction 1. For 0 <t <T, the motion of the particle is best described by which of the following for 2(t): (a) Ae* (b) + C) e (d) At - Ben + C, for some constants A, B, C. 2 O(c) Old) O(a) O(b) 2.
