Q1 a 260- metal bar 150 long and having a resistance of 100

Reference no: EM13353978

Q1. A 2.60- metal bar, 1.50 long and having a resistance of 10.0 rests horizontally on conducting wires connecting it to the circuit. The bar is in a uniform, horizontal, 1.60- magnetic field and is not attached to the wires in the circuit.

What is the acceleration of the bar just after the switch S is closed?

Q2. What friction torque is necessary to reduce its angular speed from 90.0 {rm rpm} to 45.0 {rm rpm} in a time interval of 32.0 {rm s}?
