    E Field in a shell(!!!!!!)

    I have a shell with an inner radius 2m and an outer radius 3m and a cahrge q on the shell(distributed) , why is the E field at 1m is zero(charge enclosed is zero inside the sphere i can obtain it is zero but why doesnt the E field lines go into the shell)(this can be either insulating or conducting) thank you...

    If the shell is made of a conducting material, then the field in the cavity and in the material would always be zero. But you have mentioned it may be non-conducting. Then some special charge distributions are necessary for the field to be zero at 1 m. You are missing some important info here.
