NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 12
Two point charges, q1 and q2, are separated by a distance r. If q1 is doubled and the distance is halved, by what factor does the force between them change?
A
8 times
B
4 times
C
2 times
D
No change
Correct Answer
Option A
Detailed Explanation
According to Coulomb's law, force is proportional to the product of charges and inversely proportional to the square of the distance. Doubling q1 and halving r results in a force increase by a factor of 8.
