In front of an earthed conductor, a point charge +q is placed as shown in figure: 
Select the correct alternatives.

Inside the conductor, electric field due to the point charge is non zero.

On the surface of conductor, at some points, charges are negative and at some points, charges may be positive distributed non uniformly. 

Inside the conductor, electric field due to the point charge is zero.

On the surface of conductor, the net charge is always negative.
