An alpha particle is fixed at the origin of coordinates. A neutral sodium atom is fixed at the position< 1.3, 0, 0> \mu m. Be sure to show all of your work and reasoning in your solutions to this problem.
1. What is the value of the electric field at the position of the sodium atom due to the presence of the alpha particle? (HINT: Remember that electric field is a vector quantity.)
2. What is the value of the electric dipole moment induced in the sodium atom?
3. What is the value of the force (vector) exerted on the neutral sodium atom with the alpha particle?
4. What is the value of the electric field at the position of the alpha particle? (What causes this electric field? Is it reasonable for you to use the approximate large-distance result for this solution? Why or why not?)
5. (There are no calculations in this part - only physical reasoning is needed!) Let's say that the sodium atoms were now replaced by a sulphur atom.
