Study Notes

Electrostatic Force and Permittivity

The SI unit of vacuum permittivity, ε0, is Farads per meter (F/m).

Electrostatic Force and Distance

The magnitude of the electrostatic force is inversely proportional to the square of the distance between two point charges.

Electrostatic Force Between Charges

The electrostatic force between two charges with different signs is attractive.

Formula for Electrostatic Force

The formula for the electrostatic force between two point charges q and Q at a distance r is F = (k * q * Q) / r^2, where k is Coulomb's constant.

Effect of Distance on Electrostatic Force

If the distance between two point charges is doubled, the electrostatic force becomes one-quarter of its original value.
