Hi guys I always get confused when I do the right hand rule like here when I apply it to this problem I am getting different answer than what the book have.
A uniform magnetic field B, with magnitude 1.2 mT, points vertically upward throughout the volume of the room in which you are sitting. A proton with kinetic energy of 5.3 MeV moves horizontally to the north through a certain point in the room. What magnetic deflecting force acts on the proton as it passes through this point ? The proton mass is 1.67 * 10^-27 kg.
so Fb = 6.1 * 10^-15 N; the book then says the force is sideways in horzontally to the east. I am getting it pointing in the z direction even when using cross product
FB = q<v,0,0> x <0,B,0>
Fb = qvB k^ direction
