Question

2. An electron and a proton are separated by 5 cm:

a) what is the magnitude of the force on the electron?
b) What is the net force on the system?
​

Answer 1

a) the charge of an electron is equivalent to the magnitude of the elementary charge but barring a negative sign since the side of the elementary charge is roughly 1.602 * 10 - 19 Columbus then the charge of the electronic is-1.602 * 10 - 19

b) b=2T on the electron moving in the magnetic field
