Homework Statement
A proton moves in a horizontal plane with a velocity v. It is found that when there is a magnetic field of 10(power - 2)T (magnitude) pointing from west to east, the magnetic force on the proton has a magnitude of 3.2 x 10(power of -16)N and points downwards. It is also found of that when a magnetic field of 10(power - 2)T pointing from south to north, the magnetic force on proton has a magnitude of 3.2 x 10(power - 16)N and points downward direction. Determine the magnitude and direction of the velocity.
I guess I'm required to find velocity and also the angle. Any ideas?
Homework Equations
F = qvB sin (theta)
The Attempt at a Solution
3.2 x 10(power - 16) = 1.6 x 10 (power - 19) * v * 10(power - 2) sin (theta)
I'm stuck here. i don't know how to continue on to find the velocity and also the theta.
Is there any other ways to find it?
