Homework Statement
What is the force on an electron with a velocity v = (2i – 3j) Mms-1 in a magnetic field B = (0.8i +
0.6j – 0.4k) T
Homework Equations
F=qvBsinθ
The Attempt at a Solution
using cross product I got: (1.92i + 1.28j + 5.77k)10^-13 N which is the listed correct answer.
My question is since this was an electron, why the value wasn't negative 1.92i, etc. Wouldn't the charge have contributed to the direction? Can someone please explain this to me?
Thanks
