NEET Physics Coulomb's Law MCQ Question
Two point charges, q1 and q2, are separated by a distance of 10 cm in vacuum. If q1 = 2 μC and q2 = 3 μC, what is the magnitude of the force between them?
5.4 N
5.4 × 10^2 N
5.4 × 10^-2 N
5.4 × 10^-4 N
Correct Answer
Detailed Explanation
Using Coulomb's law, F = k * (|q1 * q2|) / r^2, and substituting k = 8.987 × 10^9 Nm^2/C^2, q1 = 2 × 10^-6 C, q2 = 3 × 10^-6 C, and r = 0.1 m, the force is calculated as 5.4 × 10^2 N.
