NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Refer to the diagram showing two point charges q1 and q2 separated by a distance r. Which statement about the forces between them is correct?
A
The force is independent of the signs of q1 and q2.
B
The magnitude of the force increases if the distance r is halved.
C
The force is zero if q1 and q2 have different magnitudes.
D
The direction of force is always towards q1.
Correct Answer
Option B
Detailed Explanation
According to Coulomb's law, the force between two point charges varies inversely with the square of the distance between them, so halving the distance increases the force by a factor of four.
