Question

A charge Q = 4.35 x 10-04 C is distributed uniformly along a rod of length 2L, extending from y = -26.6 cm to y = +26.6 cm, as shown in the diagram above. A charge q = 8.05 x 10-06 C, and the same sign as Q, is placed at (D,0), where D = 18.5 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/2L)dy
C)The magnitude of the force on charge q due to the small segment dy is dF=(kqQ/2Lr*r)dy
D)The net force on q in the x-direction does not equal zero.
E)The total force on q is generally in the southeast direction.
