Question

The law, governing the force acting between two electric charges known as

• A. Ampere's law
• B. Ohm's law
• C. Faraday's law
• D. Coulomb's law

Hint:

Associate the laws with their domains: - \textbf{Coulomb} \(\rightarrow\) Force between static charges. - \textbf{Ohm} \(\rightarrow\) Voltage, current, resistance in circuits. - \textbf{Ampere} \(\rightarrow\) Magnetic field from current. - \textbf{Faraday} \(\rightarrow\) Induced EMF from changing magnetic flux.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question asks to identify the fundamental law of electrostatics that describes the force between stationary electric charges.
Step 2: Detailed Explanation:
(A) Ampere's law: Relates the integrated magnetic field around a closed loop to the electric current passing through the loop. It is a fundamental law of magnetostatics.
(B) Ohm's law: States that the current through a conductor between two points is directly proportional to the voltage across the two points (\(V=IR\)). It deals with electric circuits.
(C) Faraday's law of induction: A fundamental law of electromagnetism that predicts how a changing magnetic field will interact with an electric circuit to produce an electromotive force (emf).
(D) Coulomb's law: States that the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them. This is the law that governs the force between electric charges.
Step 3: Final Answer:
The law that describes the force between two electric charges is Coulomb's law. Therefore, option (D) is correct.
