A long straight wire lies on a horizontal table and carries a current of 2.00 µA. In a vacuum, a proton moves parallel to the wire (opposite the current) with a constant speed of 1.90E4 m/s at a distance d above the wire. Determine the value of d. You may ignore the magnetic field due to the Earth.(adsbygoogle = window.adsbygoogle || []).push({});

ok so we have

0.000002 A

19000 m/s proton with mass and charge

the only problem i have is trying to understand what is going on in the problem and what needs to be balanced... once i understand what needs to be equated the physics behind it becomes more apparent.... can anyone give me a brief explanation of what needs to be understood to solve this?
