Question

A proton is occupying a region where there is an electric field (E=195 N/C) in the positive y-direction and a magnetic field (B=11.7 mT) directed out of the page. The directions and strengths of these fields do not change, but the forces created by one or both of them may change. The picture below shows the path taken by the proton due to these influences assuming it started from the origin (point A).

a.) What is the magnitude and direction of the total force on the proton at point A (where v=30 km/s)? It is standard to state the direction as an angle measured from the positive x-axis.

b.) What is the work done on the proton in moving it from point A to point B? Assume the vertical scale is .0513m.

c.) What is the magnitude and direction of the total force on the proton at point B?

d.) What is the work done on the proton in moving it from point A to point C?

e.) Indicated the directions of the electric and magnetic forces at point D?
