Apendulum is rigidly fixed to an axle held by two supports so that it can swing only in a plane perpendicular to the axle. the pendulum consists of a mass m attached to a massless rod of length (. the supports are mounted on a platform which rotates with angular velocity ω. find the pendulums stable equilibrium position and frequency for small amplitude oscillations, when ω is constant.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
