1. 11/12 points | 4/4 submissions Last Response | Show Details All Responses Notes Two rings of radius 5 cm are 20 cm apart and concentric with a common horizontal x - axis. The ring on the left carries a uniformly distributed charge of + 35 nC, and the ring on the right carries a uniformly distributed charge of - 35 nC. What is the electric field due to the right ring at a location midway between the two rings? = < 22539.56521 [22500] , 0 [0] , 0 [0] > N/C What is the electric field due to the left ring at a location midway between the two rings? = < 22539.56521 [22500] , 0 [0] , 0 [0] > N/C What is the net electric field at at a location midway between the two rings? = < 45079.13043 [45100] , 0 [0] , 0 [0] > N/C If a charge of -9 nC were placed midway between the rings, what would be the force exerted on this charge by the rings? = <-405712.1738
