55. A ring-shaped conductor with radius a = 2.50 cm has a total positive charge Q = + 0.125nC, uniformly distributed over its entire circumference, as seen in Figure 21.24. The center of the ring is at the origin of coordinates O. a) What is the electric field (magnitude and direction) at point P, which is on the y-axis at r = 40.0 cm? b) At point P in the previous subsection, a point charge q = -2.0nC is placed at the center of the ring.a point charge q = -2.50 uC is placed at point P in the previous paragraph.What are the magnitude and direction of the force exerted by the charge q on the ring?
