An electron is released from rest 2.0 cm from an infinite charged plane. It accelerates toward the plane and collides with a speed of 1.0 x 10^7 m/s
A) What is the surface charge density of the plane in C/m^2?
First find the electric field of an infinite charged ...
The solution first finds out the electric field of the infinite charged plane. It then shows how to calculate the surface charge density of the plane and the time required for the electron to travel.
