There Is A Naturally Occurring Vertical Electric Field Near The Earth S Surface That Points Toward The Ground In Fair W 1 (18.28 KiB) Viewed 34 times

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 100.0 N/C. A spherical pollen grain with a radius of 13.0 µm is released from its parent plant by a light breeze, giving it a net charge of -1.00 fC (where 1 fC = 1 x 10-¹5 C). What is the ratio of the magnitudes of the electric force to the gravitational force, Felectric/Fgrav, 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.
