Question: Q. 4. Law stating that “force is directly proportional to product of charges and inversely proportional to square of separation between them” is called (a) Newton’s law. (b) Coulomb’s law. (c) Gauss’s law. (d) Ohm’s law.
Show Answer
Solution:
Ans. Correct option : (b)
Explanation: 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 charges and inversely proportional to the square of the distances between them.
