NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 12
Two point charges, q1 and q2, are placed at a distance r apart in a vacuum. If the charges are doubled and the distance is halved, by what factor does the force between them change?
A
16 times
B
8 times
C
4 times
D
2 times
Correct Answer
Option A
Detailed Explanation
According to Coulomb's Law, the force is proportional to the product of the charges and inversely proportional to the square of the distance between them. Doubling both charges and halving the distance increases the force by a factor of 16.
