Question

The above figure shows the paths of three particles moving perpendicular to a uniform magnetic field. Select the color of the path which corresponds to:

red,blue,or green: A particle that has no charge.

red,green, or blue: A particle that has negative charge.
red,green, or blue: A particle that has positive charge.


Now assume the particle is an electron and that its initial velocity is 312.4 m/s to the right. If the magnitude of the magnetic field is 0.74 T, what is the magnitude of the force on the particle?

Explanation / Answer

1)green: no charge

red: negative

blue: positive

2)F = v*Bsin(90) = 312.4*0.74 = 231.176 N
