# A long, straight wire lies on a horizontal table and carries a current of 1.21 µA. In a vacuum, a proton moves parallel to the wire (opposite the current) with a constant velocity of 34500 m/s at a constant distance d above the wire. Find the value of d. The acceleration of gravity is 9.8 m/s 2 and the permeability of free space is 1.25664 × 10−6 T · m/A. Ignore the magnetic field due to the Earth. Answer in units of cm.
