In the figure (see attached) what is the velocity of the charged particle to the nearest tenth of a m/s that will allow it to travel undeflected through the crossed magnetic field if E = 6852 N/C and B = 3.6 T?

2. Relevant equations

F = E*q + q*V*B

3. The attempt at a solution

Okay, so this is an online physics practice thing (for Giancolli) I was assigned for AP work. It's known for giving wrong (but close) answers, so don't be afraid to tell me that I'm doing this right (or wrong). But the answer I got is very close to the answer it gave me.

Anyway, here is my attempt:

E*q = q*V*B

cross out q

E = V*B

V = E/B

E = 6852 N/C

B = 3.6 T

V = 1903.3 m/s

Thanks,

Jordan
