Question: an electron circles at a speed of 9740 ms in...

Question details

An electron circles at a speed of 9740 m/s in a radius of 2.56 cm in a solenoid. The magnetic field of the solenoid is perpindicular to the plane of the electron's path.

The charge on an electron is 1.60218 * 10^(-19) C and its mass is 9.10939 * 10^(-37) kg. Find the strenght of the magnetic field inside the solenoid in T.

b) Find the current in the solenoid if it has 35.4 turns/cm.
