4.2.5.2 Electric fields

Spec reference: 4.2.5.2 (physics only).

Triple-only content in this dot

• Charged objects create electric fields strongest near the object.
• Force on a second charge increases as distance decreases.
• Draw/interpret field pattern for an isolated charged sphere and link to electrostatic effects.

Exam quick-check

• Can I identify this as a triple-only point from wording in the question?
• Can I apply the correct equation/idea with units and a clear conclusion?
