Practice Problems on Electric Flux
Problem 1: Calculate the electric flux through a surface of area 1.414 m² when an electric field of 5 N/C makes an angle of 45 degrees with the surface.
Problem 2: A plane surface has an electric field of 100 N/C directed perpendicular to it. Calculate the electric flux through the surface if the area is 10 m².
Problem 3: Given a surface of area 5 m2 and the electric filed in the region as 10 N/C. The flux passing through the surface is 0. What is the angle between the area vector and electric field vector?
Problem 4: Can an object having a considerable area when placed in a considerable electric field having 0 electric flux passing through it? If yes explain.
What is Electric Flux?
Electric flux is a fundamental concept in physics that helps us understand and quantify the electric field passing through a given surface. It provides a means to describe the flow of electric field lines through an area. Electric flux forms the basis of Gauss’s Law, to calculate the net charge enclosed inside a given Gaussian surface, which says that the flux through a surface will be the result of the total (or net) charge enclosed inside it.
In this article, we will learn about the basics of electric flux, its types, electric flux density, and electric flux through various types of surfaces.
