At some instant, an alpha particle(q=+2e) has the coordinates(3.0,0.0,0.0)(nm) and is moving along the positive x-axis with 500km/s while an electron at (0.0,4.0,0.0)(nm) is moving along the negative y-axis with 1000km/s.
1. Find the magnitude and direction of the total magnetic field at the location(3.0,4.0,0.0)(nm)
2. Find the magnitude and direction of the magnetic forces felt by the electron and alpha particle.
