Physics-Coulomb's Law
NEET Physics Coulomb's Law MCQ Question
Type: MCQ-numerical-Easy-Class 12
Two point charges, q1 = 2 μC and q2 = -3 μC, are placed 0.5 meters apart in a vacuum. Calculate the magnitude of the force between them using Coulomb's Law. (Use 1/4πε0 = 9 × 10^9 N m²/C²).
A
0.216 N
B
08 N
C
16 N
D
0.432 N
Correct Answer
Option C
Detailed Explanation
Using Coulomb's Law: F = k * |q1 * q2| / r². Substituting the given values: F = (9 × 10^9) * (2 × 10^-6) * (3 × 10^-6) / (0.5)² = 2.16 N.
