Electrostatic Potential Energy Calculator

Have you ever wondered how much energy exists between two charged particles? Our Electrostatic Potential Energy Calculator makes it simple. You don’t need to be a physicist to use it just enter the charges and distance, and you’ll instantly get the energy value in joules. This tool is designed to help students, teachers, and science lovers understand and calculate electrostatic energy in seconds.

What Is Electrostatic Potential Energy?

Electrostatic potential energy is the stored energy between two electric charges. It depends on the amount of charge each particle carries and how far apart they are. When the charges are close together, the energy increases. When they move apart, the energy drops.

You can think of it like stretching a rubber band the closer the charges are, the stronger the pull or push between them.

Electrostatic Potential Energy Formula

The formula used to find the electrostatic potential energy is:

Ue = k × q1 × q2 / r

Where:

• Ue = Electrostatic Potential Energy (Joules)
• k = Coulomb’s constant (8.9875517923 × 10⁹ N·m²/C²)
• q1 = Charge of particle one (Coulombs)
• q2 = Charge of particle two (Coulombs)
• r = Distance between the two charges (meters)

This formula comes from Coulomb’s Law and shows how electric charges interact.

How To Use The Electrostatic Potential Energy Calculator

Using this calculator is as easy as counting to three.

1. Enter the charge of the first particle (q1).
2. Enter the charge of the second particle (q2).
3. Enter the distance between them (r).
4. Click “Calculate.”

You’ll instantly get the electrostatic potential energy in joules. You can also switch units between coulombs, meters, and smaller or larger energy values like millijoules or kilojoules.

Example Calculation

Let’s look at a quick example:

• q1 = 14 C
• q2 = 12 C
• r = 50 m

Now, plug the values into the formula:

Ue = (8.9875517923 × 10⁹ × 14 × 12) / 50

Ue = 3.01 × 10¹⁰ Joules

So, the electrostatic potential energy between these charges is 3.01 × 10¹⁰ J.

Final Verdict

If you’re studying electric forces or working on physics problems, this calculator is your quick helper. It’s built to make science fun, fast, and frustration-free. Just input, calculate, and learn. With a clean interface and instant results, you’ll understand electrostatic potential energy better than ever.

Frequently Asked Questions (FAQs)

What is measured by the Electrostatic Potential Energy Calculator?

It measures the energy stored between two electric charges due to their interaction.

What units are used in the result?

The result is shown in joules (J), but you can also view it in kJ, MJ, or smaller units like mJ and μJ.

What happens if the distance is zero?

If the distance between charges is zero, the energy becomes undefined because dividing by zero is impossible.

Is this calculator suitable for classroom use?

Yes! It’s a great learning tool for physics students and teachers who want quick, accurate results.

Can I use this for negative charges?

Absolutely. The sign of the result indicates attraction (negative) or repulsion (positive).
