Electric field at far away distance r

WebThe electric potential due to a point charge is, thus, a case we need to consider. We can use calculus to find the work needed to move a test charge q from a large distance away to a distance of r from a point charge q. Noting the connection between work and potential W = − q Δ V, as in the last section, we can obtain the following result. WebFeb 20, 2024 · The electric potential V of a point charge is given by (19.3.1) V = k Q r ( P o i n t C h a r g e). where k is a constant equal to 9.0 × 10 9 N ⋅ m 2 / C 2. The potential at infinity is chosen to be zero. Thus V for a point charge decreases with distance, whereas E for a point charge decreases with distance squared: (19.3.2) E = F q = k Q r 2.
