A tiny spherical oil drop carrying a net charge q is balanced in still air with a vertical uniform electric field of strength 5 10 7 81   Vmñ1 . When the field is switched off, the drop is observed to fall with terminal velocity 2 × 10ñ3 m sñ1 . Given g = 9.8 m sñ2 , viscosity of the air = 1.8 × 10ñ5 Ns mñ2 and the density of oil = 900 kg mñ3 , the magnitude of q is :
