Several auxiliary activities allow students to focus on the geometric/physical meaning of the distance formula, charge densities, and steady currents. It does not store any personal data. A uniform electric field is generated between . 26 0 obj <> endobj Due to the nature of these cars, race parameters can easily be changed to encourage challenge and variation. Hence the net field is zero. Hence, a uniformly charged ring behaves as a point charge when the observation point is at a considerable distance from the charged ring compared to the ring's radius. The Electric Field for uniformly charged ring or electric field in general is defined as the force experienced by a unit positive charge placed at a particular point is calculated using.
