An electron moves with a speed of 5.0 x 10^4m/s
perpendicularto a uniform magnetic field of .20t. what is the
magnitude ofthe magnetic force on the electron?

Explanation:

Given that,

Speed of the electron,

Magnetic field, B = 0.20 T

We need to find the magnitude of magnetic force on the electron. The formula for the magnetic force is given by :

Here,

, q is the charge on electron

So, the magnitude of the magnetic force on the electron is . Hence, this is the required solution.
