Important Questions on Electric Flux and Gauss's Law
Charges are uniformly distributed in three dielectric solid spheres of radii and respectively , as shown in the figure. If magnitudes of the electric fields at point at a distance from the centres of spheres are respectively, then :

The figure below depict two situations in which two infinitely long static line charges of constant positive line charge density are kept parallel to each other. In their resulting electric field, point charges and are kept in equilibrium between them. The point charges are confined to move in the -direction only. If they are given a small displacement about their equilibrium positions, then the correct statement (s) is (are)

Consider a uniform spherical charge distribution of radius centered at the origin . In this distribution, a spherical cavity of radius, centered at with distance (see figure) is made. If the electric field inside the cavity at position is , then the correct statement is / are:

A cubical region of side a has its centre at the origin. It encloses three fixed point charges, at at at . Choose the correct option(s).

Two nonconducting solid spheres of radii and having uniform volume charge densities and , respectively, touch each other. The net electric field at a distance from the centre of the smaller sphere, along the line joining the centre of the spheres, is zero. The ratio can be:

Two nonconducting spheres of radii and and carrying uniform volume charge densities and , respectively, are placed such that they partially overlap, as shown in the figure. At all points in the overlapping region,


A point charge is placed just outside an imaginary hemispherical surface of radius as shown in the figure. Which of the following statements is/are correct?
