Phys 112-01 Re-Test 2 Name: Socutions Page 2 1. (20 pts.) A current balance apparatus (like the one you used in lab) has two parallel wires as shown in the following diagram. The upper wire has length 26.5 cm, while the lower wire has length 36.0cm. A current J is flowing in the lower wire to the left, while a current of equal magnitude flows in the upper wire to the right. A series of small mass- es m can be placed on the top wire, and the current J required to return the top wire to its equilibrium balance condition is recorded for each mass. According to Excel, m=(1.73 x 107ky ANP What is the equilibrium center-to-center separation of the bars? am Le I Cy B= B chue te Iptton wei at Locator , ny “LL 6 *P 1 arR Mag Foe om dsp ute 2 Fa ELE aail Fe ay TT, be : mag ATR Hee LT, ty L hens “ama “mg rg JO Sr Be Ay l an ky * 7.73%00 Ao la alg [273 «1077 J (Ut xo”) (0. 245°) RT (4-8) (7.93 x17)
