Answer in units of T.011 10.0 points Two long parallel wires are separated by 12 cm. One of the wires carries a current of 21 A and the other carries a current of 89 A. Determine the magnitude of the magnetic force on a 3.6 m length of the wire carrying the greater current. Answer in units of mN. 012 10.0 points A long, straight wire lies on a horizontal ta- ble and carries a current of 1.88 /A. In a vacuum, a proton moves parallel to the wire (opposite the current ) with a constant veloc- ity of 44900 m/s at a constant distance d above the wire. Find the value of d. The acceleration of gravity is 9.8 m/s and the permeability of free space is 1.25664 x 10 6 T . m/A. Ignore the magnetic field due to the Earth. Answer in units of cm
