A thin, uniform rod with negligible mass and length 0.200m is attached to the floor by a frictionless hinge at point P (as shown in fig) A horizontal spring with force constant k=4.80Nm^-1 connects the other end of the rod to a vertical wall. The rod to a vertical wall. The rod is in a uniform magnetic field B=0.340T directed into the plane of the figure. There is current I=6.50 A in the rod, in the direction shown. When the rod is in equilibrium and makes an angle of 53.0^@ with the floor, is the spring stretched or compressed?
