A point charge moving in a magnetic field of 1.24 Tesla experiences a force of 0.813E-11 N. The velocity of the charge is perpendicular to the magnetic field
The speed of the charge is 0.410E8 m/s. Calculate the magnitude of the charge
Magnitude = 1.6x10^-19 C
The path of the charge in the magnetic field is a circle. Assume that the charge is positive and has a mass of 1.673E-27kg, the mass of a proton. What is the radius of the circle?
