Question: 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
Options
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
