Question

A charge Q = 1.10 x 10-04 C is distributed uniformly along a rod of length 2L, extending from y = -15.2 cm to y = +15.2 cm, as shown in the diagram above. A charge q = 1.20 x 10-06 C, and the same sign as Q, is placed at (D,0), where D = 57.5 cm. Consider the situation as described above and the following statements. If the statement is true, answer `T', if it is false, answer `F', and if the answer cannot be determined from the information provided, answer `C'. For example if `B' and `C' are true and there is not enough information to answer `D' and the rest are false, then answer `FTTCF'. A)The net force on q in the y-direction does not equal zero. B)The charge on a segment of the rod of infinitesimal length dy is given by dQ=(Q/L*L)dy C)The magnitude of the force on charge q due to the small segment dy is dF=(kqQ)dy/(16L*Lr*r) D)The net force on q in the x-direction equals zero. E)The total force on q is in the east direction.
