A spherical rain drop of radius 1.0 mm has a charge of + 2nC. The electric field in the vicinity is 2000 N/C downward. The terminal speed of an identical but uncharged drop is 6.5 m/s. The drag force is related to the drop's speed by Fd = bv2 (turbulent drag rather than viscous drag). Calculate the terminal speed of the charged rain drop.
