Two electric dipoles aligned parallel to each other and having the same axis exert a force F on each other, when at a distance d apart. If the dipoles are at distance 2d apart, then the mutual force between them would be

3. In a coaxial cable having a conducting core and a conducting jacket, which Bessel function could be used to describe the radial dependence of the guided fields? Give explanations for your answers.

1) A permeant dipole moment p moves with a constant velocity vin +x direction. Let o be the shortest vector drawn from a point charge +0 on the -y axis to the path of the particle. The direction of p is given by Tv. v To Q Path of Particle a) Find the magnitude and direction of the torque on the dipole when it is at a distance r from the point charge + at time t. b) Assume that the particle moves so fast that the orientation of the dipole does not change while the particle is near the point charge +Q. Which component of the angular momentum L changes along V. c) Find the change in this component of the angular momentum along
