Problem 18P

Problem 18P

CE A velocity selector is to be constructed using a magnetic field in the positive y direction. If positively charged particles move through the selector in the positive z direction, (a) what must be the direction of the electric field? (b) Repeat part (a) for the case of negatively charged particles.

Step-by-Step Solution:

Solution 18 P:

Step 1 of 2:-

a)

Here, we have to find the direction of the electric field.

The magnetic field is in +ve y direction.

The positively charged particles were moving in +ve z direction.

So, the magnetic force is in which is in -ve x direction.

The net force must be zero on the particle, in order to keep it moving in the +ve z direction. So, the electric field must be in the +ve x direction.
