What are electric fields? (AQA A-Level Physics): Flashcards

Region where charged particles experience a force

Always assumed positive

Point radially outward

From positive to negative

Stronger electric field

$F = \frac{Q_1Q_2}{4\pi\varepsilon_0r^2}$

$8.85 \times 10^{-12}$

To avoid distorting the field being measured

As point charge at centre

Electrostatic many orders of magnitude greater
