in millikan oil drop expt. what is the terminal speed of an unchanged drop of radius 2 multiply by 10 raise to power -5 m and density 1.2 multiply by 10 raise to power 3 kg per m cube take viscocity of air at the temperature of the expt to be 1.8 multiply by 10 raise to power -5 pa.s how much is the viscous force on the drop at that speed neglect buoyancy of the drop due to air?
