Question
An electric dipole is kept in the electric field produced by a point charge.
Options
A.dipole will experience a force.
B.dipole will experience a torque.
C. it is possible to find a path (not closed) in the field on which work required to move the dipole is zero.
D.dipole can be in stable equilibrium.
Solution
In all orientations, dipole experiences force, but does not experience torque if dipole has its dipole moment along or opposite to ELOF.
Dipole can never be in stable equilibrium & work done in moving dipole along an EPS of point charge Q will be zero.
