## Homework Statement

A magnetic field of 0.0200 T (up) is created in a region.

a) Find the initial magnetic force on an electron initially moving at 5.00 x 10^6 m/s (N) in the field.

b) What is the radius of the circular path? Make a sketch showing the path of the electron.

## Homework Equations

F=qvB

r=mv / qB

## The Attempt at a Solution

a)

I have already determined that a) is 1.16 x 10^-14 N, my question is how do I use the right hand rule to determine direction? Since the velocity is (N) I point my thumb north and since B is (up) I have been pointing my fingers upwards. Therefore my palm is pushing East. Is this correct?

b)

I found that r=1.4 x 10^-3 m so the magnetic force for also be (East)??

Some help with the right hand rule, specifically to this question would be appreciated.
