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 m apart in vacuum. What is the magnitude of the force between them?
A
16 N
B
32 N
C
08 N
D
0.54 N
Correct Answer
Option B
Detailed Explanation
Using Coulomb’s Law: |F| = (1/(4πε₀)) * |q1 * q2| / r² = 8.987 × 10⁹ Nm²/C² * (2 × 10⁻⁶ C * 3 × 10⁻⁶ C) / (0.5 m)² = 4.32 N.
