At t = 0, a rectangular coil of resistance R = 2 Ω and dimensions W = 3 cm and L = 8 cm enters a region of constant magnetic field B = 1.6 T directed into the screen as shown. The length of the region containing the magnetic field is LB = 15 cm. The coil is observed to move at constant velocity v = 5 cm/s.

What is the force required at time t = 0.8 sec to maintain this velocity?

F(0.8 sec) =
