A charge `q_(0)` is transported from point A to B along the arc AB with centre at C as shown in figure near a long charged wire with linear density A. lying in the same plane. Find the work done in doing so.

" A charge "q_(0)" is brought from infinity to the centre of a dipole.The work done is "

For an infinite line of charge having linear charge density lambda lying along x-axis the work done in moving a charge q form C to A along CA is
