#6.2.4a
electric potential at a point as the work done in bringing unit positive charge from infinity to the point; electric potential is zero at infinity
#6.2.4b
electric potential \(V = \dfrac{Q}{4πε_0r} \) at a distance r from a point charge; changes in electric potential
#6.2.4c
capacitance \(C = 4πε_0R \) for an isolated sphere
Derivation expected from equation for electric potential and \(Q = VC\).
#6.2.4d
force–distance graph for a point or spherical charge; work done is area under graph
#6.2.4e
electric potential energy = \(Vq = \dfrac{Qq}{4πε_0r} \) at a distance r from a point charge Q.
