Problem: Two parallel, straight wires are 7.0 cm apart and each carries an 18.0 A current in the same direction. One wire is securely anchored, and the other is attached to a movable cart. If the force needed to move the wire when it is not attached to the cart is negligible, with what force does the wire pull the cart? Both wires are 50.0 m long. Note that the dyne is the unit of force in the cm, g, s system of units (often called the "cgs" system). A) 9300 dynes B) 370 dynes C) 660 dynes D) 4600 dynes

🤓 Based on our data, we think this question is relevant for Professor Stadler's class at LSU.
