Question

3) Three long wires (2 m long) are arranged in an equilateral triangle with a side length of 10 cm. The view is edge on (two wires coming out of the paper, one going in). Find: a) the net magnetic field vector at the center of the triangle, and b) the net force yector at point P (the midpoint of a side) 10A 10A 5A

That's what I was thinking, thank you. Could you please explain part a?
