NEET Physics Electric Force MCQ Question
Consider three charges q₁, q₂ and q₃ each equal to q, at the vertices of an equilateral triangle of side l. What is the force on a charge Q placed at the centroid of the triangle?
3Qq / (4πε₀l²)
2Qq / (4πε₀l²)
Qq / (2πε₀l²)
0
Correct Answer
Detailed Explanation
The net force on the charge Q at the centroid due to the symmetrical arrangement of the charges q₁, q₂, and q₃ will cancel out, resulting in zero net force.
