ELECTRICITY SAMPLE PROBLEMS

PARTICLE TRAJECTORY IN E&M FIELDS

A charged particle's trajectory inside a region with uniform electric and magnetic fields is investigated. Analytical solution is obtained.

Electric Field inside a Cavity in a Charged Insulating Sphere

Suppose you form an off-centered spherical cavity inside a charged insulating sphere. Can you find the electric field inside this cavity?

Electric Field at the Center of an n-sided Polygon

An n-sided regular polygon possesses a positive charge q at each of its vertices. Find the net electric field at the center.

ELECTRIC CHARGES AND OSCILLATION

Stable and/or Unstable equilibrium points for a three electric charge system is investigated. Frequency of oscillations is determined.

Planar Charge Distribution and Charge in Oscillation

The Electric Field due to Planar Charge distribution is found. A point charge is put in a simple harmonic motion. #electricity #oscillations
