Problem 33P

A “pure” dipole p is situated at the origin, pointing in the z direction.

(a) What is the force on a point charge q at (a, 0, 0) (Cartesian coordinates)?

(b) What is the force on q at (0, 0, a)?

(c) How much work does it take to move q from (a, 0, 0) to (0, 0, a)?

Solution 33P

Step 1 of 4:

A pure dipole is situated at the origin and it is pointing direction

In this question, we need to find the force on a point at

In part b, we need to find the force acting on charge q at

In part c, we need to find the work done in moving point charge from to

Part a:
