Table of Common Terms
To aid in understanding and utilizing the Magnitude of Electric Force Calculator, here’s a table of common terms and their definitions:
| Term | Definition |
|---|---|
| Electric Force (F) | The force exerted by one charged particle on another, measured in Newtons (N). |
| Coulomb’s Constant (k) | A fundamental constant used in calculating electric force, valued at approximately 8.988 x 10^9 N * m^2/C^2. |
| Charge (q1, q2) | The amount of electric charge in a particle, measured in Coulombs (C). Charges can be positive or negative. |
| Distance (r) | The separation between the centers of the two charged particles, measured in meters (m). |
Example of Magnitude of Electric Force Calculator
Let’s consider two particles where the first particle has a charge of +2 Coulombs (q1 = 2 C) and the second particle has a charge of -3 Coulombs (q2 = -3 C). They are placed 0.5 meters apart from each other (r = 0.5 m). We want to calculate the magnitude of the electric force between these two particles.
We use the formula:
F = k * q1 * q2 / r^2
Plugging in the values:
k= 8.988 x 10^9 N*m^2/C^2q1= 2 Cq2= -3 Cr= 0.5 m
Calculation:
F = (8.988 x 10^9) * (2) * (-3) / (0.5^2)
Let’s calculate this value.
F = -107.856 x 10^9 N
The negative sign indicates the direction of the force. In the context of electric forces, this means that the force is attractive because the charges are opposite. However, when discussing the magnitude, we’re interested in the size of the force, which is 107.856 x 10^9 Newtons.
