In Millikan’s oil drop experiment, an oil drop is
observed to move vertically upward. The upward
motion of the drop is due to
(a) gravity (b) viscosity
(c) buoyancy (d) electric field

(D) Electric Field
Because in Millikan’s oil drop experiment the oil drop is balanced in the electric field . Equation => qE = mg
Where q = charge of oil drop
E = Electric field
m = mass of oil drop
g = gravity acceleration(9.8m/s2)
