[15 Points] The figure shows a rod with its central axis along the y-axis and a ring with its central axis along the x-axis. • The rod, located at a distance y = 12 [cm] from the origin, has a length L = 4 [cm] and a charge Qrod = 81 [pc] uniformly distributed. • The ring, located at a distance d = 20 [cm] from the origin, has a radius R = 5 [cm] and a charge Qring = 26 [pc] uniformly distributed. y [cm] R x [cm] 1. [2 Points] Calculate the magnitude of the electric field created by the rod at the origin. Erod [N/C] 2. 12 Points) What is the direction of the electric field vector created by the rod at the origin 3. [2 Points] Calculate the magnitude of the electric field created by the ring at the origin. Ering [N/C) 4. [2 Points) What is the direction of the electric field vector created by the ring at the origin 5. [2 Points] Calculate the linear charge density of the rod and select the corresponding unit y= Downward Upward To the right To the left 6. [2 Points] Calculate the linear charge density of the ring. Aring 7. [3 Points] The rod is moved upward so that the magnitude of the electric field of the rod is now 27. 5 [N/C). Find the new distance y between the origin and the rod. [cm]
