A long straight wire carries a current, I=2A. A semi-circular conducting rod is placed beside it on town conducting parallel rails of negligible resistance. Both the rails are parallel to the wire. The wire, the rod, and the rails lie in the same horizontal plane, as shown in the figure. Two ends of the semi-circular rod are at distances 1cm are 4cm from the wire. At time t=0, the rod starts moving on the rails with a speed of v=3.0m/s.
A) Maximum current through R is 1.2x10^(-6)A
B) Maximum current through R is 3.8x10^(-6)A
C) Maximum charge on capacitor is 8.4x10^(-12)C
D) Maximum charge on capacitor is 2.4x10^(-12)C
