A technician wraps wire around a tube of length 33 cm having a diameter of 7.9 cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 600 turns of wire.
Find the self-inductance of this solenoid.
If the current in this solenoid increases at the rate of 3 A/s, what is the self-induced emf in the solenoid?
A particle with a charge of -1.5uC and a mass of 2.5x10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 42 m/s. The only force acting on the particle is the electric force. (a) Which point is at..
