Electric field vectors for two circular parallel plates

See attached file for clarity. Consider two circular parallel plates of radius R separated by a distance d  R. Assume that these plates have uniformly distributed surface charges of Q and -Q. Electric field vectors in the region between the plates will all point perpendicular to the plates from the positive

binomial approximation for a three dimensional potential field

Consider a dipole consisting of two charged particles on the x axis, one with positive charge q+ located at x=+1/2d and one with negative q- charge located at x=-1/2d a) Derive an exact expression for the three dimensional potential field created by this dipole at a point P whose coordinates are {x, y, and z} b) Use the bi

Electrostatic energy stored in the capacitor.

(1) A parallel plate capacitor of plate area 2m2 and palte separation 5mm is charged to 10,000V in vacuum. Compute the capacitance, charge, charge density, field strength in the space between the plates and also the energy stored in the capacitor. (2) The charging battery is removed and the space between the plates is filled

Understanding the electric field

An electron is accelerated eastward at 1.4x109 m/s2 by an electric field. Determine the magnitude and direction of the electric field.

Electric and potential fields...(solid conducting core)

Consider a concentric spherical system made up of the following parts: A solid conducting core radius a with total charge Qc , surrounded by a conducting shell of inner radius b and outer radius c. The shell has total charge -Qc . For each of the appropriate regions, find Qenclosed , E and V. Make the appropriate set of gr

Compute the direction and magnitude of the electric field.

In Figure A1 in the attachment, the boundary between two ideal dielectrics is shown. Near the boundary, on Er1 side, the electric field is measured and found to be perpendicular to the boundary and equal to 100 V/m. a) What is the direction of the electric field E, near that boundary and on Er2 side? b) What is the magnitu

Application of Biot Sarvat's Law.
