A proton enters a region with an Electric Field that has Equipotential Lines as shown:
30V
25V
20V
15V
10V
a. Draw Electric Field vectors at points A, B, C.
b. Where is the Electric Field stronger, at point A or B? Why? Explain.
c. If the distance between the 20V line and 15V line at B is 0.25 cm, what is the magnitude of the Electric Field at B? (show all your work!)
d. If a proton is at point B, what is the direction of the Force on the proton?
e. If the proton starts at rest at A, what is its speed at point C? (show all your work!)
