On a semicircular ring of radius 4R charge 3q is distributed in such a way that on one quarter q is uniformly distributed and on another quarter 2q is uniformly distributed Along its axis a smooth nonconducting and uncharged pipe of length 6 R is fixed axially as shown A small ball of mass m and charge q is thrown from one end of pipe with speed u The speed u so that ball will come out from the other end of pipe is 3q A u 40 Rm B u 2q 7q 40 Rm 3q C u21401c Rm 9q D u 40 Rm
