Problem: An electron and a proton are each moving at 795 km/s in perpendicular paths as shown in (Figure 1) .Part AFind the magnitude of the magnetic field the electron produces at the location of the proton.Part BFind the direction of the magnetic field the electron produces at the location of the proton.

FREE Expert Solution

Part A

Magnetic field:

B=μ0qvsinθ4πr2

From Pythagoras theorem, the separation between the electron and the proton is given by:

r=re2+rp2=(5.00×10-9)2+(4.00×10-9)2
