Question
Find the distance between point charges q1 = 26.0 μC and q2 = 47.0 μC, if a force of 5.70 N is acting between them.
Correct Answer
Option B is the correct answer.
Detailed Explanation
Using Coulomb's law: F = k q1 q2 / r² => r = √(k q1 q2 / F) = √((9×10^9 × 26×10^-6 × 47×10^-6) / 5.70) = 1.389m.
Hint
Apply Coulomb's law and solve for distance.
