Two point charges q1andq2 are placed in an external uniform electric field as shown in figure. The potential at the location of q1andq2 are V1andV2, i.e., V1andV2 are potentials at location of q1andq2 due to external unspecified charges only. Then electric potential energy for this configuration of two charged particle is i.e Two point charges [...]

A plane sheet has a uniformly distributed charge. Origin is selected at the middle of the sheet (in yz plane). A charge +Q is moved from point A (10a, 2a,0) to point B (10a,0,2a) along a circle and then to point C(10a, 0, 0). If the initial electrostatic potential energy is U0, what will be [...]

An electric dipole of dipole moment p is oriented parallel to a unifrom electric field E, as shown It is rotated to one of four orientations shown below. Rank the final orientations according to the change in the potential energy of the dipole-field system, most negative to most positive. An electric dipole of dipole moment [...]
