Electrostatic Force Calculator
Electric force is one of the fundamental forces of nature and plays a crucial role in physics, electronics, and modern technology. Whether you are studying electrostatics, analyzing particle interactions, or working on electrical systems, understanding how electric charges interact is essential. The Electric Force Calculator is a powerful and easy-to-use tool designed to calculate the force between two electric charges accurately and instantly.
This calculator uses established physical principles to determine both the magnitude of the electric force and whether the force is attractive or repulsive, helping users gain clear and practical insights into charge interactions.
What Is Electric Force?
Electric force is the force of attraction or repulsion between electrically charged objects. It occurs because electric charges create electric fields that exert forces on other charges within those fields.
- Like charges repel each other
- Opposite charges attract each other
This force is responsible for many everyday phenomena, from static electricity to the behavior of particles at the atomic level.
Coulomb’s Law Explained Simply
The electric force between two charges is calculated using Coulomb’s Law, which states that the force is:
- Directly proportional to the product of the charges
- Inversely proportional to the square of the distance between them
In simpler terms:
- Larger charges produce stronger forces
- Greater distance reduces the force rapidly
The Electric Force Calculator applies this principle instantly, saving you from complex calculations.
Why Use the Electric Force Calculator?
Manually calculating electric force can be time-consuming and prone to mistakes, especially when dealing with very small charges or large constants. This calculator helps you:
- Instantly compute electric force magnitude
- Identify whether the force is attractive or repulsive
- Avoid calculation errors
- Save time during study or analysis
- Improve understanding of electrostatic interactions
It’s suitable for both educational and practical use.
Key Features of the Electric Force Calculator

How to Use the Electric Force Calculator
Using the calculator is straightforward and takes only a few steps:
Step 1: Enter Charge 1
Input the first electric charge in coulombs (C). This value can be positive or negative.
Step 2: Enter Charge 2
Enter the second electric charge in coulombs (C). The sign of the charge matters for determining force type.
Step 3: Enter Distance
Provide the distance between the two charges in meters (m). The distance must be greater than zero.
Step 4: Click Calculate
Press the Calculate button to instantly see:
- Electric force magnitude (in newtons)
- Force type (attractive or repulsive)
Step 5: Reset (Optional)
Use the Reset button to clear inputs and start a new calculation.
Example Calculation
Let’s look at a simple example:
- Charge 1 = +2 × 10⁻⁶ C
- Charge 2 = –3 × 10⁻⁶ C
- Distance = 0.5 meters
Result:
- The calculator determines the magnitude of the electric force
- Since the charges have opposite signs, the force is attractive
This example clearly demonstrates how both charge value and distance affect the force and how the calculator simplifies the process.
Understanding Force Type: Attractive vs Repulsive
The calculator automatically identifies the force type based on the charges:
- Both charges positive or both negative → Repulsive force
- One positive and one negative → Attractive force
This feature helps users immediately understand the nature of interaction without additional analysis.
