1) A charge Q is distributed uniformly on a non-conducting ring of mass M and radius R. The ring is dropped from a height h and Falls to the ground through a non-uniform magnetic field B(r). Consider that the plane of the ring remains horizontal during this fall (50 point). a) Explain qualitatively why the ring rotates as it falls. b) Using Faraday flux rule show the velocity of the center of mass of the ring when it hits the ground is Q²R² Vcm= 2gh- 4M² [B₂(0) - B₂(h)]2 Hint: Consider the rotation and torque of the ring appearing for the fall.
