If a spherical conductor comes out from the closed surface of the sphere then total flux emitted from the surface will be
$\frac{1}{{{\varepsilon _0}}} \times $ (the charge enclosed by surface)
${\varepsilon _0} \times $ (charge enclosed by surface)
$\frac{1}{{4\pi {\varepsilon _0}}} \times $ (charge enclosed by surface)
$0$
The charge $q$ on a capacitor varies with voltage as shown in figure. The area of the triangle $AOB $ represents
An electric line of force in the $xy$ plane is given by equation ${x^2} + {y^2} = 1$. A particle with unit positive charge, initially at rest at the point $x = 1,\;y = 0$ in the $xy$ plane
What is called Gaussian surface ?
What will be the total flux through the faces of the cube as in figure with side of length $a$ if a charge $q$ is placed at ?
$(a)$ $A$ $:$ a corner of the cube.
$(b)$ $B$ $:$ midpoint of an edge of the cube.
The electric field in a certain region is acting radially outward and is given by $E =Ar.$ A charge contained in a sphere of radius $'a'$ centred at the origin of the field, will be given by
