NEET Physics Electric Potential MCQ Question
Two charges, 5 × 10⁻⁸ C and -3 × 10⁻⁸ C, are located 16 cm apart. If the potential at infinity is zero, what is the distance from the 5 × 10⁻⁸ C charge along the line joining the two charges where the electric potential is zero?
9.6 cm
8 cm
6.4 cm
12.8 cm
Correct Answer
Detailed Explanation
The electric potential V at a point on the line joining the two charges is given by the equation V = k(q1/r1 + q2/r2) where r1 and r2 are distances from the point to charges q1 and q2, respectively. Set V = 0 and solve for the distance from the 5 × 10⁻⁸ C charge.
