Homework Statement
A particle with a unit charge enters a magnetic field B = i + j with velocity v = 17k . Find the magnitude and direction of the force on the particle.
The Attempt at a Solution
Had no issues finding the magnitude. However, when finding the direction of the force on the particle, the textbook says by the right hand rule the force is applied at an angle of 135 degrees with the positive x-axis in the xy-plane. I understand how to apply the right hand rule and show the general direction of the vector ( I sketched it), but how did they come up with 135?
Thank you
