An electron is moving in a concentric circular orbit inside a solenoid of radius 4.89 cm, in such a manner that it grazes the inside surface of the coil at all the points of its orbit. The speed of the electron is 9,820 m/s, and the solenoid has 3.50×103 turns/m. Assume the coils of the solenoid are so thin the electron moves essentially at the radius of the solenoid. What electric current is passing through the solenoid?
