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
r = √(kq₁q₂/F) = √((9×10⁹ × 26×10⁻⁶ × 47×10⁻⁶)/5.70) = 1.389m
Hint
Rearrange Coulomb's Law to solve for radius.
