Charged Ring: in the Figure, a Ring 0

Question 53

Multiple Choice

Charged ring: In the figure, a ring 0.71 m in radius carries a charge of + 580 nC uniformly distributed over it. A point charge Q is placed at the center of the ring. The electric field is equal to zero at field point P, which is on the axis of the ring, and 0.73 m from its center. (ε0 = 8.85 × 10-12 C2/N ∙ m2) The point charge Q is closest to Charged ring: In the figure, a ring 0.71 m in radius carries a charge of + 580 nC uniformly distributed over it.
