The formula to calculate Coulomb's Constant (k) is:
k=F⋅d2q₁⋅q₂
Where:
Let's say the force (F) is 1 N, the magnitude of charge 1 (q₁) is 1 C, the magnitude of charge 2 (q₂) is 1 C, and the distance between the charges (d) is 1 m. Using the formula:
k=1⋅121⋅1=1
So, Coulomb's constant (k) is 1 N·m²/C² in this example.
