Applying the Electric Field Model using Formulas

How to apply the electric field model using formula?

In this post, we are applying the electric field model to account for and quantitatively analyse interactions between charged objects, as a part of the Prelim Physics course under the module Electricity and Magnetism and sub-part Electrostatics. The relationships that are used are:

  • \vec{F} = q \vec{E}
  • E = \frac{V}{d}
  • F = \frac{1}{4 \pi \epsilon _{0}} \frac{q_{1} q_{2}}{r^{2}}

 

The following videos calculate the magnitude of an electric field using various relationships.
