Aparallel-plate capacitor has a plate area of 0.3 m2 and a plate separation of 0.1 mm. if the charge on each plate has a magnitude of 5 × 10–6 c then the force exerted by one plate on the other has a magnitude of about:

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
