Question

An electric field strength at a far - off point P due to a point charge, +q located at the origin, O is 100 millivolts/metre. The point charge is now enclosed by a perfectly conducting hollow metal sphere with its centre at the origin, O. The electric field strength at the point, P

• 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

Answer 1

The correct option is A remains unchanged in its magnitude and direction

Ans : (a)

The radially outward field is normal to conductor and no induction effects E is same.
