As shown in the figure,a point charge `Q` is placed at the centre of conducting spherical shell of inner radius a and outer radius `b`.The electric field due to charge `Q` in three different regions `I,` II and `III` is given by `(I:rb` )

Options

A. `E_(1)=0,E_(II)=0,E_(III)=0,`
B. `E_(1)!=0,E_(II)=0,E_(III)=0,`
C. E_(1)=0,E_(II)=0,E_(III)!=0,
D. E_(1)!=0,E_(II)=0,E_(III)!=0,

Answer

D
