# Point Electric Charge Calculator

## The calculator for calculating a point electric charge helps you to calculate a point electric charge by the force acting on the charge and the strength of the electric field, and also by the strength of the electric field and the distance from the charge, the units of measurement can be any prefixes Si. The calculator automatically converts one unit to another and gives a detailed solution. The calculator calculates: Point electric charge if known: the force acting on the given charge and the electric field strength.Point electric charge, if known: electric field strength and distance from the charge.

Point Electric Charge Q if Known: The Force F Acting on the Given Charge and the Electric Field Strength E

A point electric charge Q is equal to the ratio of the force F acting on a given charge and the strength of the electric field E at a given point. The SI unit of charge is - Coulomb (C).
Force F =
Electric Field Strength E =
The SI unit of Q

Point Electric Charge Q if Known: Electric Field Strength E and Distance r From the Charge

A point electric charge Q is equal to the ratio of the product of E and r2 and k, where E is the electric field strength, r is the distance from the charge, k - is electrostatic constant k = 8.9875517873681764 × 109 The SI unit of charge is - Coulomb (C).
Electric Field Strength E =
Distance r =
The SI unit of Q

Also, to calculate the charge q1 by the force of interaction F, the distance r and the charge q2, you can use the Coulomb's Law calculator.
