A charge q is removed from A to B in the region of a fixed ideal dipole P find the work done on the charge (Assume gravity free space )

Text Solution

Verified by Experts

W`= DeltaU= q(pcos(pi-theta))/(4piepsilon_(0)r^(2))-q(pcostheta )/(4piepsilon_(0)r^(2))`
`=(-2pqcostheta)/(4piepsilon_(0)r^(2))=(pqcostheta)/(2piepsilon_(0)r^(2))`
