Although the term voltage is used every day, in physics it is a measure of a fairly abstract
quantity called Electric Potential. Its important to distinguish electric potential from electric
potential

Week 3 Tutorial Solutions
1.
The vector for a planar surface area A is composed of the
magnitude A and a direction perpendicular, to the plane (its normal).
Then, through the mathematical definition of flux: E = E.A, E =
EAcos(). (refer to diagram)

would be some force on it with a Y component - this is unlikely to
produce equilibrium

NOTES:
Charge comes in two varieties: positive and negative. Like charges repel each other
whereas unlike charges attract.
Coulombs Law was found experimentally by looking at these forces, F for two known
charges
