What is the unit of electrostatic force?

The unit of electrostatic force is the Newton (N) in the International System of Units (SI). The electrostatic force, also known as Coulomb's law, describes the force of attraction or repulsion between charged objects. It is given by the equation:

F = k * (|q1 * q2|) / r^2

Where:

F is the electrostatic force between two charged objects, measured in Newtons (N).
k is Coulomb's constant, approximately equal to 8.99 x 10^9 N·m²/C² in SI units.
q1 and q2 are the magnitudes of the charges on the two objects in Coulombs (C).
r is the distance between the centers of the two charged objects in meters (m).
So, the unit of electrostatic force (F) in SI units is the Newton (N).
