1. The problem statement, all variables and given/known data Two straight wires, each with a resistance of 0.170 ohm and a length of 3.90m, are lying parallel to each other on a smooth horizontal table. Their ends are connected by identical, non-conducting, light springs, each spring having an unstretched length of 1.08 cm. A wire of negligible resistance connects the wires at one end. When a switch is closed to connect a battery with a voltage of 49.0 V between the other ends of the wires, the wires move apart and come to rest with a separation of 1.57 cm Question: Find the force constants of the springs. 2. Relevant equations F=-kx (F/L)=(u0I1I2)/2Pi r 3. The attempt at a solution I tried to solve using the equations above for K, and does not work.
