The cyclotron consists of two dees in strong magnetic field where oscillating electric field is applied from an oscillator. In this, magnetic field is perpendicular to electric field which exists only across the gap between the dees. The charged particle gets accelerated, while crossing the gap and moves along the circular paths with radius r…

Hello students in this session we will learn about Gauss’s law in electrostatics and also learn some important points about it. So lets start… Gauss’s law According to Gauss’s law, the total electric flux passing through any closed surface is equal to the net charge q enclosed by it divided by ε0. ϕ = q/ε0…
Hello students, so first of all we understand, what is the electric flux?Electric flux measures how much the electric field ‘flows’ through an area. Or we can say that Electric flux over an area in an electric field is a measure of the total number of electric field lines crossing a surface. Mathematically, we can…
