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 $R^{\prime }(R^{\prime }>R)$ from ‘q’. Then the resultant electric field will be best represented for region $r$ > R by: (where $r$ is the distance of the point from q)

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

$\because$ For conducting shell, there is no electric field inside the sphere due to outer charges. So the only electric field will be due to 'q'.
