Question - A thin, uniform rod with negligible mass and length 0.200 m is attached to the floor by a frictionless
hinge at point P (Fig). A horizontal spring with force constant k = 4.80 N/m connects the other end of
the rod to a vertical wall. The rod is in a uniform magnetic field B = 0.340 T directed into the plane of
the figure. There is current I = 6.50 A in the rod, in the direction shown.
(a) Calculate the torque due to the P magnetic force the rod, for an axis at P. Is it correct to take the
total magnetic force to act at the center of gravity of the rod when calculating the torque? Explain.
(b) When the rod is in equilibrium and makes an angle of 53.0o with the floor, is the spring stretched
or compressed?
(c) How much energy is st ...Read More
