Problem: An electron is accelerated by a 6.6kV potential difference. The charge on an electron is 1.60218 x 10-19 C and its mass is 9.10939 x 10-31 kg.
Part A: How strong must a magnetic field be experienced by the electron if its path is a circle of radius 5.6 cm?
I want help to find how strong a magnetic field must be experienced by the electron.
