Fo = ofor pans a} and b}\ a) What is the direction of the current, clockwise or counter-<:lockwise, that needs to flow in order\ to lift the ball up along the z direction?\ b) If the ball mass is and the spring constant is Q.,l N/cm, then what is the value of the\ resultant current in the circuit needed to hold the top of the ball at point z = 30 cm ?\ c) Now we remove the voltage source, and directly connect the two wires with a conductor.\ Assume the ball is equivalent to a 0.02 .Q resistor. You grab the ball, and move it in the +z\ \ problem 1.7\ A square loop (with dimensions shown below) is placed between two fixed infinite wires, 31 a\ distance x from wire I. They are all on the same surface (XY plane), with the loop free to move\ without friction . Ignore the effect of the magnetic field produced by the IA source. The system is\ in free space
