Slader If the field is 300 N/C near the Earth’s surface, use Gauss’s Law to calculate the total electric charge on the Earth, assuming the electric field is radially downward and constant in magnitude over the whole surface of the Earth.

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 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
