Consider a thin non conducting ring of radius a, which has a charge Q uniformly spread around it. Find an expression for the electric force vector on a point charge q placed at point P, which is located on the x axis of the ring at a distance of x from the center. Verbally explain your reasoning. Let x=6 cm and Q=6 microC. Calculate the magnitude (in N) and the direction of the elctric force
