Question

Find the force on an electron passing through a 0.50 T magnetic field if the velocity of the electron is 4.0 × 106 m/s. (answer in scientific notation, include sign)

Answer 1

Given:

The strength of the magnetic field is B = 0.5 T

The velocity of the electron is

`v=\text{ 4}*10^6\text{ m/s}`

The charge on an electron is

`q=-1.6*10^(-19)\text{ C}`

To find the force.

Step-by-step explanation:

The force can be calculated as

`\begin{gathered} F=qvB \\ =1.6*10^(-19)*4*10^6*0.5 \\ =3.2*10^(-13)\text{ N} \end{gathered}`
