The electric field strength at a far-off point P due to a point charge, +q located at the origin O is 100 milliVolt/meter. The point charge is now enclosed by a perfectly conducting hollow metal sphere with its centre and the origin O. The electric field strength at the point, P is
(a) Remains unchanged in its magnitude and direction
(b) Remains unchanged in its magnitude but reverse in direction
(c) Would be that due to a dipole formed by the charge, +q, at O and -q induced
(d) Would be zero
This question was addressed to me in an interview for internship.
