The electric field strength at a distance 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
