Question
A charge ′q′ is placed at the centre of a conducting spherical shell of radius R, which is given a charge Q. An external charge Q′ is also present at distance R′ (R′ > R) from ′q′. Then the resultant field will be best represented for region r < R by:
[ where r is the distance of the point from q ]

[ where r is the distance of the point from q ]

Options
A.

B.

C.

D.

Solution
Inside the given sphere, there will not be any effect of external electric field. So net electric field will only be due to point charge ′q′ at centre.
∴ Graph is (A)
∴ Graph is (A)
