Physics — Electrostatics
Charges, fields, and the laws that connect them.
See how a charge held between two fixed charges oscillates with simple harmonic motion when displaced from the center.
See how the field at a fixed point changes as you vary α and β, and drag a charge element along the rod.
See how the electric field along the axis of a charged ring rises to a maximum and then falls, and why it is zero at the center.
See how the fields of individual charges placed around a ring add together, and how they approach a continuous ring of charge as you add more.
See how a charged particle moves through a uniform electric field, following a curved path set by the force acting on it.
See the field line patterns for different charge configurations, from a single point charge to dipoles, sheets, and shells.
