Three conducting spherical shells have charges q,-2q and 3q as shown in figure. Find electric Potential at point P as shown in figure.

A point charge q is placed at a distance d from centre of a uniformly charged conducting spherical shell of radius R and having charge Q as shown. Magnitude of electric field intensity at point P just inside the shell due to charge on shell is

Consider a metallic hollow sphere with its centre at point O. Point charge +Q is kept in the vicinity of the given sphere as shown in the figure. If the sphere is electrically neutral, then calculate the electric potential at point A due to induced charges on the sphere only.

A uniformly charged non-conducting spherical shell is given +q charge and a point charge -q is placed as shown. The electric field lines will be

A uniformly charged non-conducting spherical shell is given +q charge and a point charge -q is placed as shown. The electric field lines will be

Consider an initially neutral hollow conducting spherical shell with inner radius r and outer radius 2r. A point charge +Q is now placed inside the shell at a distance r/2 from the centre. The shell is then grounded by connecting the outer surface to the earth. P is an external point at a distance 2r from the point charge +Q on the line passing through the centre and the point charge +Q as shown in the figure. The magnitude of the force on a test charge +q placed at P will be

A small spherical conductor 'A' of radias 'a' is initially charged to a potential 'V' and then placed inside an uncharged spherical conducting shell 'B' of radius 6a as shown. The potential of the spherical conductor 'A' after closing the switch S is
