$15.$ Two parallel transmission line wires carrying currents in the same directions are separated by a distance of $1$ m apart and have a resistance of $2$ kilo$-$ohms each. The wires are both $4$ m in length and connected to a Potential difference of a $1000$ kilo$-$volts. Which of the following is true for the foree that the two transmission lines exert on each other?

$($i$)$ Force exerted on the wires is attractive and is equal to $0\mathrm{.}2$ N

$($ii$)$ Force exerted on the wires is repulsive and is equal to $0\mathrm{.}2$ N

$($iii$)$ Force exerted on the wires is attractive and is equal to $3\mathrm{.}2$ N

$($iv$)$ Force exerted on the wires is repulsive and is equal to $3\mathrm{.}2$ N
