Question

I looked at the other problems like this but they wanted anactual answer. However for this HW we have to use variables theanswer that I got is is 1(B*i*d*t)/(m)   but it doesnot work.  It wants it in variable form of m,d,B,iand t.    Appreciate anyones ideas. Thanks.

I looked at the other problems like this but they wanted anactual answer. However for this HW we have to use variables theanswer that I got is is 1(B*i*d*t)/(m) but it doesnot work. It wants it in variable form of m,d,B,iand t. Appreciate anyones ideas. Thanks. 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 field Bvec. Generator G produces aconstant current i in the wire and the rails (even as thewire moves). Find the velocity of the wire's motion as a functionof time, assuming it to be stationary at t = 0. (Usem, d, B, i and t asnecessary, where all quantities are in SI units. Enter the sign ofthe expression, taking right to be positive.) v = 1

Explanation / Answer

v = v0 + at (1) stationar at t=0 --> v0 = 0 F = ma --> a= F/m = i*B*d/m Apply right hand rule Forces on the wires are cancelled out There is only force on the rail, and it points to negativedirection (1)--> v = - i*B*d*t/m You got the right value but the force is toward negativedirection.
