What is the electric field on the surface of a thin conducting spherical shell containing uniform charge q?

The field is

            E  =  1 / (4 pi ε₀)    Q / R²        directed radially outward from
                                                            the center of the shell.

R is the radius of the spherical shell.

Notice that the field is exactly the same as the field due to a point-charge
with magnitude 'Q' that's located at the center of the sphere.

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
