. A thin metallic spherical shell contains a charge Q on it

A point charge q1 is placed at the centre O of the shell and another charge q is placed at P, at a distance d, (d > r) from the centre as shown in the figure. The incorrect option is


A. Force on q1 due to the charge on shell [Q and induced charges] is towards right.

B. Force on q1 due to all the charges [Q, q and the induced charges) is zero.

C. Force on q1 due to q is towards left

D. Force on q due to Q and q1

Best Answer

Ans: D

Sol: Uniformly charged metallic sphere can be treated as a point charge for calculation of electric field at an external point.
