Question

(a) Define electric flux. Is it a scalar or a vector quantity ?
A point charge q is at a distance of d/2 directly above the centre of a square of side d, as shown in the figure. Use Gauss’ law to obtain the expression for the electric flux through the square.
(b) If the point charge is now moved to a distance ‘d’ from the centre of the square and the side of the square is doubled, explain how the electric flux will be affected.

Answer 1

Answer:

electric flux through a given area held inside the electric field the measure of total number of electric lines of force passing normally through that area.. it is a scalar quantity.
