Textbook Problem

The electrons in a particle beam each have a kinetic energy K. Find the magnitude of the electric field that will stop these electrons in a distance d, expressing the answer symbolically in terms of K, e, and d. Should the electric field point in the direction of the motion of the electron, or should it point in the opposite direction?

To determine
The magnitude of electric field.

Explanation

The work done is,

W=Fdcosθ

  • F is the electric force.
  • d is the distance.

The force on the charge is opposite to the direction of motion. Therefore, θ=180ο .

W=Fdcos180ο=Fd

The electric force is,

F=qE
