The figure shows a wire that has been bent into a circular arc of radius 27.2 cm, centered at O. A straight wire OP can be rotated about O and makes sliding contact with the arc at P. Another straight wire OQ completes the conducting loop. The three wires have cross-sectional area A-1.32 mm' and resistivity p -4.05 x 10"0m, and the apparatus lies in a uniform magnetic feld of magnitude 8 0.640 T directed out of the hgure. Wire OP begins from rest at angle -0 and has constant angular acceleration of 16.0rad/s. As functions of e (in rad), find (a) the loop's resistance and (b) the magnetic flux through the loop (c) For what eis the induced current maximum and (d) what is that maximum?
