If both of two point charges are doubled and the distance between them is also doubled, the force between them ____.

Correct answer D. remains the same

Explanation

F ∝ q₁q₂/r². Doubling both charges multiplies the numerator by 4, and doubling r multiplies the denominator by 4. The two effects cancel, so the force is unchanged.
