A long straight wire carries a current I = 2A. A semi circular conducting rod is placed beside it on two conducting parallel rails of negligible resistance. Both rails are parallel to wire. The wire , the rod, and the railslie in same horizontal plane as shownin figure. Two ends of semi circular rod are at distances 1 cm and 4 cm from the wire. At time t = 0 rod starts moving on the rails with a speed v = 3 m/s. A resistor R= 1.4 ohm and capacitor `C_0 = 5 mu F` are connected in series between rails. At time t = 0, `C_0` is uncharged. Which of the following statements is/are correct?

Options

A. maximum current through R is 1.2 x `10^-6` A
B. maximum current through R is 3.8 x `10^-6` A
C. maximum charge on capacitor `C_0` is `8.4 xx 10^-11` C
D. maximum charge on capacitor `C_0` is 2.4 x `10^-12` C

Answer

A
