When sugar is poured from the bag into the sugar bowl, the rubbing of the sugar grains creates a static electric charge that repels the grains and causes sugar to go flying out in all directions. If two sugar grains each acquire a charge of 7.10×10-11 C at a separation of 322 micrometers, with what force will they repel each other?

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?
