Figure shown a closed surfce which intersects a conducting sphere. If a positive charge is placed at the point P, the flux of the electric field through the closed surface

Figure shows a closed surface which intersects a conducting sphere. If a positive charge is placed at point P, find the sign of flux passing through the curved surface S. .

As shown in figure a closed surface intersects a spherical conductor. If a negative charge is placed at point P. What is the nature of the electric flux coming out of the closed surface?

Fig shows three point charges +2q, -q and + 3q , What is the electric flux due to this configuration thorugh the surface S ?

A point charge Q is placed at the centre of a hemisphere. Find the electric flux passing through flat surface of hemisphere.

A point charge Q is placed at the centre of a hemisphere. Find the ratio of electric flux passing through curved andplane surface of the hemisphere.

a point charge q is placed at the centre of a cylinder of length L and radius R the electric flux through the curved surface of the cylinder is

The figure shows equipotential surfaces due to two poit charges +3Q and -Q placed at a separation d. (a) Will the shape of epuipotential surface be spherical very close to both the point charges? What shape of equipotentials will be seen at very far away points from the pair of charges. (b) Find the distance of point P from the negative charge. (c) Find the potential of the surface marked as S_1 is the figure. (d) Consider the surface having zero potential. Write the flux of electric field through this surface
