A square region of space 43.5 m on a side has a constant magnetic field B = 7.82 T pointing into the page. A square loop of wire of side s =8.42 m and total resistance 2.88 ? also lies in the plane of the page, moving at constant speed v = 2.76 cm/s toward the y-axis that bounds the region of B.

At t = 0 s the leading edge of the loop hits the edge of the square region. Find the magnitude of the force you must apply to move the loop at constant speed:

a) at time t = 2.013 s
b) at time t = 9.98 s
