Two infinitely long parallel wires having linear charge densities \lambda_{1} and \lambda_{2} respectively are placed at a distance of R. The force per unit length on either wire will be

{2 k \lambda_{1} \lambda_{2}}/{R}

{k \lambda_{1} \lambda_{2}}/{R}

{2 k \lambda_{1} \lambda_{2}}/{R^{2}}

{k \lambda_{1} \lambda_{2}}/{R^{2}}
