There is a naturally occurring vertical electric field near the earth’s surface that points toward the ground. in fair weather conditions, in an open field, the strength of this electric field is 95.0 n/c . a spherical pollen grain with a radius of 12.0 μm is released from its parent plant by a light breeze, giving it a net charge of −0.700 fc (where 1 fc=1×10−15 c ). what is the ratio of the magnitudes of the electric force to the gravitational force, / , acting on the pollen? pollen is primarily water, so assume that its volume mass density is 1000 kg/m3 , identical to the volume mass density of water.
