Two bodies are falling with negligible air resistance, side by side, above a horizontal plane. if one of the bodies is given an additional horizontal acceleration during its descent, it
a. strikes the plane at the same time as the other body
b. strikes the plane earlier than the other body
c. has the vertical component of its acceleration altered
d. has the vertical component of its velocity altered
e. follows a straight line path along the resultant acceleration vector

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?
