WebThe Electric Field of a Line of Chargecalculator computes by superposing the point charge fields of infinitesmal charge elements The equation is expressed as `E=2klambda/r` … WebThe electric potential V of a point charge is given by. V = k q r ( point charge) 7.8. where k is a constant equal to 8.99 × 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: E = F q t = k q r 2.
