A metal ring with a total net charge Q of 6 mC is placed on XY plane. The radius of the ring is 5 meters. Find electric field that is 15 meters away from the center of the ring.

A ring of charge is centered at the origin in the vertical direction. The ring has a charge density of a = 6.93 × 10-6 C/m and a radius of R = 2.15 cm. dq Find the total electric field, E, of the ring at the point P = (1.56 m, 0.00 m). The Coulomb force constant is k = 1/(4xe0) = 8.99 × 10º N-m²/C². R dE E = N/C Find the expression for the electric field, E», of the ring as the point P becomes very far from the ring (x > R) in terms of the radius R, the distance x, the total charge on the ring q, and the constant k = 1/(4ле). E = P.
