Discussion Forum : Electric Charges Fields And Gauss Law
Question -
A solid metallic sphere has a charge + 3Q. concentric with this sphere is a conducting spherical shell having charge –Q. The radius of the sphere is a and that of the spherical shell is b. (b > a). What is the electric field at a distance R (a < R < b) from the centre.
Answer: Option C
:
C
We only need to consider the E contribution due to sphere.
Shell gives zero contribution to E at any point inside it.
Use direct formula.
E=14πϵ03QR2
E=3Q4πϵ0R2
