L shaped rod has equal and opposite charge `(+- Q)` spread along its both arms (see figure). (a) What is direction of electric field at point P? (b) Write electric potential at P.

An electric dipole consists of two charges of equal magnitude and opposite sign saperated by a distance 2 a as shown in figure . The dipole is along the x axis and is centered at the origin (A) Calculate the electric potential at point P . (B ) Calculate V at a point far from the dipole .

The figure here shows three nonconducting rods, one circular and two straight. Each has a uniform charge of magnitude Q along its top half and another along its bottom half. For each rod, what is the direction of the net electric field at point P ?

An electric dipole has the magnitude of its chawrge q and its dipole moment is p. It is placed in a uniform electric field. If the dipole moment is along the direction of the field, what is the force on its and its potential energy?

Two point charges q and -q is placed at a distance 2a apart.Calculate the electric field at a point P situated at a distance r along the perpendicular bisector of the line joining the charges. What is the electric field when r gtgt a ? Also, give the direction of electric field W.r.t. electric dipole moment? .

An electric dipole has the magnitude of its charge as q and its dipole moment is p. It is placed in a uniform electric field E. It its dipole moment is along the direction of the field, the force on it and its potential energy are, respectively.

An electric dipole has the magnitude of its charge as q and its dipole moment is p . It is placed in a uniform electric field E . If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively
