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 110.0 N/C 110.0 N/C . A spherical pollen grain with a radius of 11.0 μm 11.0 μm is released from its parent plant by a light breeze, giving it a net charge of − 0.550 fC −0.550 fC (where 1 fC = 1 × 10 − 15 C 1 fC=1×10−15 C ). What is the ratio of the magnitudes of the electric force to the gravitational force, F e l e c t r i c / F g r a v Felectric/Fgrav , acting on the pollen? Pollen is primarily water, so assume that its volume mass density is 1000 k g / m 3 1000 kg/m3 , identical to the volume mass density of water.
