A frame a bed and a sliding rod `PQ` of resistance `R`, start moving with the velocities `v` and `2v` respectively parallel to a long wire carrying steady current `I`, as shown in the figure. A. charge on the capacitor at time `t` is `q=(Cmu_(0)ivln2)/(2pi)[1-e^(-t//RC)]`B. charge on the capacitor at time `t` is `q=(Cmu_(0)ivln2)/(pi)[1-e^(-t//RC)]`C. current passing through the resistor at time `t` is `i=(mu_(0)ivln2)/(2piR)[e^(-t//RC)]`D. current passing through the capcitor at time `t` is `i=(mu_(0)ivln2)/(piR)[e^(-t//RC)]` |

Answer» `epsilon_(PC)=(vmu_(0)i)/(2pi)ln2` `epsilon_(PQ)=(2vmu_(0)i)/(2pi)ln2` `epsilon_("net")=(mu_(0)iv)/(2pi)ln2` `q=Cepsilon[1-e^(-t//RC)]` `i=(epsilon)/(R )e^(-t//RC)` |
