Question

The electric field strength at distant point, P, due to a point charge, +q, located at the origin, is 100 $\mu$ V/m. If the point charge is now enclosed by a perfectly conducting metal sheet sphere whose center is at the origin, then the electric field strength at the point, P, outside the sphere, becomes.

• A. zero
• B. 100 $\mu$V/m
• C. -100 $\mu$V/m
• D. 50 $\mu$V/m

Answer 1

The correct option is B 100 $\mu$V/m

Ans : (b)

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