A zero-resistance rod sliding to the right on two, Ask an Expert

Academics

A zero-resistance rod sliding to the right on two zero-resistancerails separated by the distance L = 0.75 m. The rails are connected by a 15.1-Ω resistor, and the entire system is in auniform magnetic field with a magnitude of 0.750 T.

(a) Find the force that must be exerted on the rod to maintain aconstant current of 0.125 A in the resistor.

(b) What is the rate of energy dissipation in the resistor? inmW

(c) What is the mechanical power delivered to the rod? in mW
