2. a. Amoveable ( massless and Frictionless ) bar with a length of L= 0.50m is being moved at a constant velocity of Lo 10 m/s from left to right along two conducting rails by an external Force, F, as Shown in the figure, IF the system is immersed in a uniform magnetic Field (out of the Paper) with magnitude 100 Tesla , what is the induced current and its direction OF the loop if the resistance 15 4.0 n2 A b. Un Polarized light with intensity Io is incident on a Series of Polarizing sheets . The first sheet has it transmission axis oriented 90 wurt+ x. A Second Polarizer has it transmission axis oriented at 45 wr+ + x, A Third Polarizer has it transmission axis oriented 16 wr+ + X, Determined the fraction of light exiting the third Sheet and Show all work? C. I a call is expanding in a magnetic Field Pointing Out From Page, in what direction is the induced current
