NEET Physics Coulomb's Law MCQ Question
Consider a diagram showing two point charges, q1 and q2, with position vectors r1 and r2, respectively. Vector F12 represents the force on q1 due to q2. Which of the following correctly describes the relationship between F12 and the permittivity of free space, ε0?
F12 is inversely proportional to ε0.
F12 is directly proportional to ε0.
F12 is independent of ε0.
F12 depends on the square of ε0.
Correct Answer
Detailed Explanation
According to Coulomb's law as expressed using the permittivity of free space, the force F12 is inversely proportional to ε0, as shown in the equation F = (1/4πε0) * (q1q2/r^2).
