10 cards from this deck
Region where charged particles experience a force
Always assumed positive
Point radially outward
From positive to negative
Stronger electric field
F=Q1Q24πε0r2F = \frac{Q_1Q_2}{4\pi\varepsilon_0r^2}F=4πε0r2Q1Q2
8.85×10−128.85 \times 10^{-12}8.85×10−12
To avoid distorting the field being measured
As point charge at centre
Electrostatic many orders of magnitude greater
