1. 	For a given charged particle of charge q :

	a. 	What is the formulae for the electric field E, in terms of 
	the position and the charge? What is the geometry of this problem?
	(symmetry of field)

	


	b. 	What is the formulae for the potential V, in terms of the
		position and the charge?





  2 .  Do these relations satisfy the equation given in the Lab Manual :
	\delta V = E* \delta d. Where d is the distance.




  3 .  What is the assumption made in the manual that allows us to use the
	equation given in 2?





Extra:
	Even without the assumption in 3 we can say something about the
electric field. Given a set of measurement \delta V, \delta d. What can be
said about the electric field and what is the mathematical theorem that
asserts that. (name and state the theorem).
