Suppose a conducting rod (mass m, resistance R) rests on twofrictionless and resistanceless parallel rails a distance l apartin a uniform magnetic field ⃗B (perpendicular to the rails andto the rod and pointing out of the paper) as shown below. At t = 0,the rod is at rest and a source of emf is connected to the points aand b. Determine the speed of the rod as a function of time

(a) if the source puts out a constant current I,
(b) if the source puts out a constant emf Eo.
(c) Does the rod reach a terminal speed in either case?
If so, what is it?


Please DO NOT just copy the answer from the textbook helpsection. I am asking this question because I do not understand the"Expert Response".

1)As shown in the figure, a uniform conducting rod of length 0.40 m and mass 0.075 kg is in rotational equilibrium about the hinge at point O. A uniform magnetic field of 0.23 T is directed out of the plane of the page, perpendicular to the rod. Due to a battery and wires not shown, there is a current of 4.0 A in the rod directed toward point O. Determine the angle θ.

2)As shown in the figure, a conducting rod with a length of 0.79 m is placed on a horizontal frictionless surface and attached to a power supply by two springs, each with a spring constant of 81 N/m. The springs are initially at their equilibrium length and are in a region where there is a uniform magnetic field of 0.17 T that is perpendicular to the frictionless surface when the power supply supplies a current that causes the wire to move in such a direction that the two springs are stretched.

A top view of a table shows an arrow field labeled vector B pointing down into the table.
