PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question
Take CBT

Question

According to Coulomb's Law, the electric force between two point charges is inversely proportional to what?
Options
A The product of the charges.
B The square of the distance between them.
Correct Answer
C The permittivity of the material between them.
D The sum of the magnitudes of the charges.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Coulomb's Law follows an inverse-square relationship, meaning as the distance (r) increases, the force decreases by the square of that distance (1/r²).

Hint

Think of the 'r' term in the denominator of the formula.
