The Answer of A conducting bar of length L rotates in a counterclockwise direction with a constant angular speed of +2.0 rad/s about a pivot P at one end, as shown. A uniform magnetic field (magnitude = 0.20 T) is directed into the paper. If L = 0.40 m, what is the potential difference, V_A − V_B? A) +24 mV B) −24 mV C) +16 mV D) −16 mV E) +32 mV
