Question 11

In a mass spectrometer's electrostatic analyzer, two flat parallel plates are separated by a distance $s\,$ and maintained at a potential difference $V$ . An ion with a charge of $+ 2 e$ is located at a distance of 0.25s from the positive plate.

What is the magnitude of the electrostatic force acting on this ion?

A

$s\,$

B

$2eVs\frac{2eV}{s}$

C

$8eV3s\frac{8eV}{3s}$

D

$8eVs\frac{8eV}{s}$
