A thin, uniform rod with negligible mass and length 0.200 m is attached to the floor by
Question:
(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 stored in the spring when the rod is in equilibrium?
