2 long parallel wires of negligible resistance are connected at one end to a resistance and at the other end to a dc voltage source.the distance between the axes of the wires is n=20 times greater than the cross sectional radius of each wire.at what value of resistance r does the resultant force of interaction between the wires turn zero.
