Question

Electric field due to wire ( (2)=frac{1}{4 pi in_{0}} frac{2 lambda_{2}}{R} )
Charge per unit length on wire ( (1)=lambda_{2} )
Force per unit length on wire
[
begin{aligned}
(1) &=lambda_{1} times E
&=lambda times frac{1}{4 pi in_{0}} frac{2 lambda_{2}}{R}
&=frac{Kleft(2 lambda_{1} lambda_{2}right)}{R}
end{aligned}
