I desperately need help, for I am quite lost on this question:
Consider the example of a positive charge moving in the xy plane with velocity v = cos(theta)x + sin(theta)y (i.e., at angle theta with respect to the x axis). If the local magnetic field is in the +z direction, what is the direction of the magnetic force acting on the particle?
Express the direction of the force in terms of theta, as a linear combination of unit vectors, x, y, and z.
F = qBV
One hint given was to find the determinant expression for the cross product, but I don't know what this means.
Thanks for any replies.
