- 3 Two Particles A And B Having Mass M And 2m And Carrying Charge Q And Q Respectively Are Attached To The Opposite E 1 (22.54 KiB) Viewed 37 times
3. Two particles A and B having mass m and 2m and carrying charge +q and -q respectively, are attached to the opposite ends of a massless non-conducting rigid rod of length L. The electric dipole so constituted is placed in the uniform external electric field E. Initially the dipole moment vector makes an angle 30° with the electric field E and then system is released from this position. Assuming gravity free space, find the net force acting on the particle A. (a) Just after the release. qE/2 (b)) When dipole moment vector becomes parallel to the electric field.
