How the charges communicate?
Electrostatic force comes from an action at a distance (via the field) and the closer
.the charges the greater the electrostatic force
.The communication between the charges goes as the speed of light
Electric Field vector E
Example (Electric field due to a ring with uniform continuous charge distribution)
A ring of radius R has a uniform positive charge distribution per unit length with total charge q.
Calculate E along the axis of the ring at point p, (see the vertical figu
Flux of the Electric field
We have three possibilities
Example (Uniform E)
The figure shows a Gaussian surface in the form of a
cylinder of radi

Orthogonal and orthonormal vectors
Definition. We say that 2 vectors are orthogonal if they are perpendicular
to each other. i.e. the dot product of the two vectors is zero.
Definition. We say that a set of vectors cfw_~v1 , ~v2 , ., ~vn are mutually
