Question

In deriving the axial electric field for the ring-shaped charge distribution and the electric field from a long line of charge, the component perpendicular to the resulting field is zero because of what physical property?a) integration b) superposition c) only net charge is important d) symmetry e) positive and negative charges

Answer 1

B) Superposition

Step-by-step explanation:

This is because the horizontal components of the electric field at a point on the axis of the ring cancel out, due to the fact that the horizontal components of the electric field due to the differential charges at opposite points of the ring point in opposite directions.
