Q722: If the distance between the charges doubles, the coulomb's force between the charges _____?

اگر چارجز کے درمیان فاصلہ دوگنا ہوجاتا ہے تو ، چارجز کے درمیان کولمب کی طاقت _____؟

Explanation

According to Coulomb’s Law, the electrostatic force $F$ is inversely proportional to the square of the distance between the charges:
$F propto frac{1}{r^2}$

If the distance doubles ( $r to 2r$ ), the force reduces to one-fourth of its original value:
$F' = frac{F}{4}$

Q723: For an electronic state s = 1, and 1 = 1, the number of possible values of total angular momentum of an electronic are _____?

Q724: The equation E = mc^2 indicates that energy _____?

Explanation

Einstein’s equation $E = mc^2$ shows that energy and mass are interchangeable, meaning mass can be converted into energy and vice versa.

This principle is fundamental in nuclear reactions, where small amounts of mass release large amounts of energy.
