You are given a potential function:
V (x, y, z) = x + 4xy + 2z2 + 1
(Units are volts and metres).
(a) Find the electric field E(x, y,z) at the origin (0,0, 0) AND at point (2, 2,2). You may leave the answers in (i,j, k) notation without finding magnitude and direction.
(b) Find the potential difference going from (2, 2, 2) to the origin (0, 0,0).
(c) How much work has to be done to move a charge -e (an electron) from (2, 2, 2) to the origin? Express you answer in both electron volts (eV) and in Joules.
Hint: use the potentials, not the electric field, to make it easy!
(d) Does the charge move spontaneously from (2,2,2) to the origin, or is an external force required to push it? Explain why.

How much current they pro vide
: Batteries are always labeled with their emf; for instance, an AA flashlight battery is labeled 1.5 volts. Would it also be appropriate to put a label on batteries stating how much current they pro vide? Why or why not?

Does the charge move spontaneously
: Find the electric field E(x, y,z) at the origin (0,0, 0) AND at point (2, 2,2). You may leave the answers in (i,j, k) notation without finding magnitude and direction.

Interpret the entries of matrix
: Using the program MatrixPowers, compute the 100th power of the transition matrix. Interpret the entries of this matrix. Repeat this with p = .2. Why do the 100th powers appear to be the same?
