Linear charge densities of two parallel wires of infinite length is lambda_(1) and lambda_(2) . Distance between two wires is R. Force acting on any one wire per unit length is ...... |

Answer» `k(lambda_(1)lambda_(2))/R`  `E_(1) = (2klambda_(1))/R` Charge on wire-2, of length I, `q=lambda_(2)l` `therefore` FORCE acting on wire-2 of length l, `F = EQ = (2klambda_(1))/R xx lambda_(2)l` `therefore` Force acting per unit length, `F/l = (2klambda_(1)lambda_(2))/R` |
