Nature of light

Light is transverse and electromagnetic radiation that exhibits the properties of a wave as well as a particle. For this reason, light is said to have a “dual nature.”

1.
Answer part (b) of the problem. Show your work.
2.
What would be the terminal velocity of the rod if all the conditions of part (b) of
the problem where held, except there was also friction with a kinetic coefficient of µg =
0.0215?
3.
Qualitatively discuss what effect considering the resistance of the
conducting rails would have on your estimate of terminal velocity. Make sure to consider
that as the rod slides, the overall resistance of the circuit increases as a function of that
distance slid. Do you think this would lead to a larger or smaller terminal velocity than the
one you calculated in part (b)?

Challenge Problem 6
A conducting bar of mass m = 18.0 g and resistance R = 1.89 N slides down two conducting rails
that are frictionless and have no electrical resistance. These rails make an angle 0 = 40.0° with the
horizontal and are separated by a distance { = 20.0 cm, as shown. In addition, a uniform magnetic
field B = 712 mT is applied vertically upward. The bar is released from rest and slides down.
(b) As the bar continues to slide, the forces approach
equilibrium. What is the induced current in the bar
when it is moving at 85.0% of terminal speed?
