Hint 1. How to approach the problem In this part of the problem, the situation is simply a specific case of the more general situation analyzed in Part B, where a body of mass m that moves at constant speed through a viscous medium experiences a retarding force Farag proportional to the speed of the body. Here, a droplet of given density falls at constant speed Vrerm through air and experiences a retarding force of magnitude Farag, which is proportional to the droplet speed. The constant of proportionality depends on the viscosity of air and the radius of the droplet. To solve this part of the problem simply anply Newton's 1st law to the droplet and solve for the droplet!'s radius
