1. Definition of Newtons per Coulomb
Newtons per coulomb (N/C) is defined as the force experienced by a unit charge placed in an electric field. Specifically, it quantifies the electric field strength, which is the force per unit charge acting on a charged particle. The relationship can be expressed as:
- Electric Field (E) = Force (F) / Charge (q)
Thus, an electric field of 1 N/C indicates that a charge of 1 coulomb would experience a force of 1 newton.
2. Formula for Calculating Electric Field Strength
The formula for calculating electric field strength in newtons per coulomb is derived from Coulomb's law. The formula is as follows:
Where:
- E = Electric field strength (N/C)
- F = Force exerted on the charge (N)
- q = Charge (C)
This formula allows scientists and engineers to determine the electric field strength in various situations, whether in a laboratory setting or in practical applications.
3. Applications of Newtons per Coulomb
The applications of newtons per coulomb are vast and varied. Here are a few key areas where this unit plays a critical role:

- Coulombs (C): The coulomb is a unit of electric charge, and understanding its relationship with newtons per coulomb is essential in electrostatics.
5. Example Calculations
To illustrate the concept of newtons per coulomb, consider a scenario where a charge of 2 coulombs is subjected to a force of 10 newtons. The electric field strength can be calculated as follows:
- E = F / q = 10 N / 2 C = 5 N/C
This example demonstrates how to apply the formula to find the electric field strength in a practical situation.
