A charge Q=7.3×10−4 C is distributed uniformly along a rod of length L, extending from =−28.8/2 cm to =+28.8/2 cm, as shown in the diagram below. A charge q=4.15×10−6 C, and the same sign as Q , is placed at (D,0), where D=55 cm. Consider the situation as described above and the following statements. Check each box that corresponds to a true statement. Select "None of the above" if none of them are true. A. The total force on q is generally in the +x direction. B. The charge on a segment of the rod of infinitesimal length dy is given by dQ=(Q/L)dy C. The y-components of the force on q cancel. D. The magnitude of the force on charge q due to the small segment dy is dF=(kqQ/4Lr2)dy E. Given that both charges are positive, the net force on q in the y direction is upwards. F. Given that both charges are positive, the net force on q in the x direction is to the left. G. None of the above.
