Answer» wo long WIRES having linear charge DENSITIES λ1 and λ2 are PLACED PERPENDICULAR to each other at SEPARATION r.To find:Value for 'n' when electrostatic force of interaction between them is proportional to r^n.Calculation:Since both the wires are considered to be infinite, the force experienced by any one of the wires will be :'k' is Coulomb's Constant, 'l' is length of the wires.So, value of n is -1.
