Question: A proton is shot perpendicularly at an infinite plane of charge. The charge density of the plane is +7.65×104 C/m2. If the proton starts out 1.05 mm from the plane, what must its velocity be so that it screeches to a halt exactly as it reaches the plane?
Please show how you obtained the answer.
