A dipole with an electric moment `vec(p)` is located at a distance r from a long thread charged uniformly with a linear charge density `lambda`. Find the force F acting on the dipole if the vector `vec(p)` is oriented along the thread

Text Solution

Verified by Experts

The correct Answer is:
(a) F=0 ; (b) `F=-(lambda p)/(2pi epsilon_(0)r^(2))` ; (c ) `F=(lambda p)/(2pi epsilon_(0)r^(2))`
