I'm having a little trouble understanding where exactly do I plug in the numbers and I don't know if I'm doing the problem right hope you can help. Thanks.
An electron moves north at a velocity of 9.8 x 10^4m/s and has a magnetic force of 5.6 x 10^-18 N west exerted on it. If the magnetic field points upward, what is the magnitude of the magnetic field?
I know the equation is B= Fmagnetic/ qv
the velocity is the qv right?
so would putting the equation like this be correct?
B= 5.6 x 10^-18/ 9.8 x 10^4
or I'm missing something here?

Yes you are missing the value of q (the charge of an electron) which is equal to 1.602e-19 C
Other then that think you've got it right.

Velocity is v and charge is q.
B= 5.6 x 10^-18/ ( 1.6 x10^-19* 9.8 x 10^4)
B = 0.00036 tesla.
====================
B= 5.6 x 10^-18/ ( 1.6 x10^-19* 9.8 x 10^4)
B = 0.00036 tesla.
