(3) A proton moves near two wires (carrying currents I, and ₂). Wire 1 is horizontal and Wire 2 is perpendicular to the page.

Assume all values to 3 sig figs.

(a) Find the net force vector on the proton due to the magnetic fields from the two currents.

(b) Find a direction that the proton could move so it feels zero magnetic force from II. (ignore I; for this part)
