A non-conducting spherical shell has an inner radius & and an outer radius 28. There are no charges at r<& where r is the distance from the center of the sphere. A total charge is distributed uniformly in the volume of the shell (between r=R kQ and r=2R) Find the magnitude of the electric field at r=1718. Express your answer in units of using two decimal R² places
