. Determine the magnitude and direction of the force between two parallel wires 20m long and 4.0cm apart (center-to center) each carrying 30A in the same direction. The radius of each wire is 1.3mm.

Hey hope you get the answer but i suck at math sorry : (

Answerboth technicians (a) and (b);

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
