Step 1
Given: Initial kinetic energy, K_initial = 4.0 × 10^-17 J Final kinetic energy, K_final = 0 J (since the electrons are stopped) Distance, d = 0.3 m Charge of electron, e = 1.6 × 10^-19 C Show more…

The electrons in a particle beam each have a kinetic energy K. What are (a) the magnitude and (b) the direction of the electric field that will stop these electrons in a distance d?
A The electrons in a particle beam each have a kinetic energy $K .$ What are the magnitude and direction of the electric field that will stop these electrons in a distance $d$ ?
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?
