The gravitational force between two masses is F. If the distance between them is halved, the force becomes MCQ with Answer and Explanation

The gravitational force between two masses is F. If the distance between them is halved, the force becomes
A. 2F
B. F/2
C. 4F
D. F/4
Answer: Option C
Solution (By JKExamLibrary)
Newton's law of gravitation: F ∝ 1/r². If distance r becomes r/2, new force F' ∝ 1/(r/2)² = 4/r² = 4F. So force quadruples. This inverse square law is fundamental for gravitational, electric, magnetic forces.

Which of the following materials is used as a fuse wire?
A. Aluminium
B. Tin-lead alloy
C. Copper
D. Silver

Correct Answer: Option B


Explanation:
Fuse wire made of alloy of tin and lead (or copper with low melting point). It has low melting point and high resistance. Copper has high melting point, not suitable for fuse. Silver expensive. Aluminium not typical.
