Help me if you can!! Particle physics!! Give it a shot!!! Pleaseee in particle physics data from fermi lab I have to find out the momentum (p) of x, y, and z. The equation is p=qBx and i have q(coulombs) and B (tesla). The data I'm looking at says cos theta x=0.47 cos theta y=-.10 cos theta z=-.88 using q=1.609E-19 and B=4 how can I find p x, p y, p z?
