Question

what is the fundamental quantity in electrostatics​

Answer 1

Explanation:

Electrostatics is the study of stationary electric charges.The direction of the electrostatic force depends upon the signs of the charges. The most fundamental electric charge is the charge of one proton or one electron.

Answer 2

The fundamental quantity in electrostatics​ is as follows:

• Electrostatics is a foundational subject in potential theory because it is where most of the equations and fundamental notions in electromagnetic theory come from.
• Electrostatics is a branch of electromagnetism that deals with the interaction of electric charges when all of them are stationary.
• In the study of electric circuits, one of the most fundamental physical quantities is a charge.
• A charge quantity that remains constant across time (i.e., time-invariant).
