Transcribed Image Text:Problem 10.9
In the center and at the edge of a metal disc with radius a = 15 cm
two sliding contacts are connected and the circuit is closed on a
resistor; the total resistance is R = 8.10- The disk is immersed
in a uniform and constant magnetic field B = 0.03 T parallel to the
axis.
To calculate:
(1) the torque M to be applied to the
disk to keep it rotating at a frequency
V = 1800 rpm,
%3D
B.
(2) the power P dissipated in the circuit
R.
under these conditions
(3) the charge q which passes through
the circuit in one minute.
