Electromagnetic Field Theory The electrical field strength at a distance point A due to a point charge +q, located at the origin, is 100 µl v/m. If the point charge is now enclosed by a perfectly conducting metal sheet sphere whose centre is at origin, A, outside the sphere, becomes - 100 μ v/m. None of above. 0. 100 μ v/m. - 100 μ v/m. None of above. 0. 100 μ v/m. ANSWER DOWNLOAD EXAMIANS APP
