WebDec 12, 2024 · Let AB be an electric dipole of charges -q and +q and distance between them be 2l. Dipole makes an angle θ in the electric field E in the direction of field. Force on the charge +q due to electric field is given by F = qE. Due to both forces are equal and opposite. Hence resultant force is zero, but they from a couple. WebApr 4, 2024 · The Electric field formula is E = F/q Where E is the electric field F (force acting on the charge) q is the charge surrounded by its electric field. If two charges, Q and q, are separated from each other by a distance r, then the electrical force can be defined as F= k Qq/r2 Where F is the electrical force Q and q are the two charges
