SPSC 25 years Past Papers 2001 to 2025

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:
$F' = frac{F}{4}$

Q1057: For an electronic state s = 1, and 1 = 1, the number of possible values of total angular momentum of an electronic are _____?

A. 2
B. 3
C. None of these
D. 4

Q1058: The equation E = mc^2 indicates that energy _____?

A. None of these
B. Is fundamentally different than mass
C. Equals mass moving at the speed of the light square
D. And mass are closely related

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.
