How does torque differ from force?
An electron and a proton are each moving at 755 km/s in perpendicular paths as shown in (Figure 1). At the instant when they are at the positions shown, find the magnitude and direction of the total magnetic field they produce at the origin. Find the magnitude and direction of the magnetic field the electron produces at the location of the proton. Find the magnitude and direction of the total magnetic and electric force that the electron exerts on the proton. Please explain all steps
