Question

A point dipole p = p ez is at the origin. At point P1 = (x1,0,0) there is a point charge e. What is the force on this charge due to the field of the dipole? What is the force on the dipole? How much work is required to take the charge from P1 to infinity if the dipole remains fixed at the origin? How much work is required to take the dipole from the origin to infinity if the charge remains fixed at P1? What is the physics underlying the simple answers to these questions?

Answer 1

solution placed at Point P, A Force on the Charge e = (X1,0,0) 3 CE Eeklo (-ez) [wlere k = uten] at Force on the dipole = Fonch Pole КРе е = 3 + As electoic Potential energy af the Charge e at Point P = 0 so work done = o JJ 47 As electric Potential energy as the di Pole to to Charge e is also Zero so work done to take the dipole from the origin to infinity is also zero Wero [Physico of electric difole]
