If the distance between two points charges is doubled and force between them will become _____?
اگر دو پوائنٹس کے چارجز کے درمیان فاصلہ دوگنا ہوجاتا ہے اور ان کے درمیان طاقت _____ بن جائے گی؟
Answer: 1/4
Explanation
According to Coulomb’s Law, force is inversely proportional to the square of distance: F∝ 1/r².
So, if distance is doubled, force becomes 1/(2)² = 1/2.
