Important questions on Gauss's Law for JEE Main and Advanced







Question 1
Consider the figure given below
Important  questions on Gauss's Law for JEE Main and Advanced
A positive charge +q is placed at corner of the cube. Find the electric flux through the right face BCGDB of the cube.
Question 2
Consider a sphere of radius r having charge q C distributed uniformly over the sphere. This sphere is now covered with a hollow conducting sphere of radius R>r.
  1. Find the electric field at point P away from the centre O of the sphere such that r<OP<R.
  2. Find the surface charge density on the outer surface of the hollow sphere if charge q’ C is placed on the hollow sphere.
 
Question 3
  1. Find the electric field inside the uniformly charged sphere of radius R and volume charge density ρ using Gauss’s law.
  2. Use Gauss’s law to find the electric field outside, at a point on the surface and at any point inside a spherical shell of radius R, carrying a uniform surface charge density σ.
