Electron Motion in a Solenoid
A tightly wound long solenoid carries a current of 1.5 A. An electron is executing uniform circular motion inside the solenoid with a time period of 75 ns. The number of turns per metre in the solenoid is_______.
[Take mass of electron me = 9 × 10–31 kg, charge of electron |qe| = 1.6 × 10–19 C,
μ0 = 4π × 10–7 ,1 ns = 10–9 s]
