A charge of 1 ìC is spread uniformly around a ring of radius 10 cm. What is the potential at a point located 5 cm from the centre, along the axis of the ring?

Question

Quizplus · Accepted Answer

The potential at a point along the axis of a uniformly charged ring is given by V = (k * Q) / sqrt(R^2 + x^2), where k is Coulomb's constant, Q is the charge, R is the radius, and x is the distance from the center. Substituting the given values, V = (9 * 10^9 * 1 * 10^-6) / sqrt(0.1^2 + 0.05^2) = 80 kV.
