the magnitude of q is
A tiny spherical oil drop carrying a net charge q is balanced in still air with a vertical uniform electric field of strength 81π/7 ×10 ^5 V/m When the field is switched off, the drop is observed to fall with terminal velocity 2×10 ^ −3 m/s Given g = 9.8 m/s^2 , viscosity of the air = 1.8 × 10^−5 Ns/m^2 and the density of oil =900 kg /m^3 , the magnitude of q is
