Question
A metal wire of mass m slides without friction on twohorizontal rails spaced a distance d apart, as in thefigure below. The track lies in a vertical uniform magnetic fieldBvec. Generator G produces a constant current i in thewire and the rails (even as the wire moves). Find the velocity ofthe wire's motion as a function of time, assuming it to bestationary at t = 0. (Use m, d,B, i and t as necessary, where allquantities are in SI units. Enter the sign of the expression,taking right to be positive.)v =
Explanation / Answer
please post the figure.
