Electron in a Solenoid#

A solenoid with 25 turns per centimter carries a current \(I\). An electron moves within the solenoid in a circle of radius 3.00\(\textrm{ cm}\). The plane of the circular motion is perpendicular to the axis of the solenoid.The speed of the electron is \(1.50\times 10^{4 } extrm{ m/s}\) \(\textrm{ m/s}\).

Question Text#
