    The discharge of the capacitor is given by
                                        V = ? e-t / RC
                               Qo / 4C = Qo / C e-t /RC
                                   0r 1/4 = 1e-t / RC
                                0ret / RC = 4
                                 0rt / RC = ln 4
                                        0r R = RC ln 4
                                        0r R = 29 k?
