Electrostatic part 17//work done rotate a dipole// Electric Charge and Field// By Er.Mahendra Nagar

The electrostatic potnetial due to an electric dipole at an equatorial point is

what is the net force on a dipole in a uniform electric field ?

The work done in moving an electric charge q in an electric field does not depend upon

An electric dipole of dipole moment vecP is placed in a uniform electric field vecE such that vecP is perpendicular to vecE . The work done to turn the dipole through an angle of 180^(@) is -

State Gauss's law in electrostatics. Using this law derive an expression for the electric field due to a uniformly charged infinite plane sheet.

(a) Derive an expression for the torque experienced by an electric dipole kept in a uniform electric field. (b) Calculate the work done to dissociate the system of three charges placed on the vertices of a triangle as shown. Here q= 1.6 xx 10^(-10)C .

The electric field at a point on equatorial of a dipole and direction of the dipole moment

The work in rotating electric dipole of dipole moment p in an electric field E through an angle theta from the direction of electric field, is:

STATEMENT -1 : A point charge be rotated in a circle around a fixed charge, the work done by electric field of fixed charge will be zero. and STATEMENT -2 : Work done is the dot product of force and displacement.

A point charge q is rotated along a circle in the electric field generated by anotherj point charge Q. The work done by the electric field on the rotatin charge in one complete revolution is
