How are two-force members and three-force members similar? 1. They both show how the magnitude of forces can be transmitted through an object.2. They both keep all the forces in parallel lines to each other. 3. They both are constrained by the EOE. 4. They both decrease magnitude as the angle to the force increases

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?
