#6.2.2a
Coulomb’s law;
\(F = \dfrac{Qq}{4πε_0r^2} \) for the force
Learners will also require knowledge of section 3.2
#6.2.2b
electric field strength
\(E = \dfrac{Q}{4πε_0r^2} \) for a point charge
#6.2.2c
similarities and differences between the gravitational field of a point mass and the electric field of a point charge
Learners will also require knowledge of 5.4
#6.2.2d
the concept of electric fields as being one of a number of forms of field giving rise to a force.
Learners will be expected to link this with 5.4
