Electric field due to point charge formula
WebAn electric field is defined as the electric force per unit charge. It is given as: E → = F → / Q. Where, E is the electric field intensity. F is the force on the charge “Q.”. Q is the charge. Variations in the magnetic field or the electric charges cause electric fields. Volt per metre (V/m) is the SI unit of the electric field. WebAug 8, 2016 · The answer is obvious if you look at the formula, ∮ E →. d S → = q ϵ o. For a symmetric distribution, you ca always take a surface such as a sphere, cylinder where the electric field is equal everywhere. If the field is equal everywhere, you can pull the field parameter out of the integral and you will be left with,
