Answer 2

The direction of the viscous force in Millikan's oil drop experiment is always downwards.

• The motion of oil drop is due to the gravitational force that's why oil drops move downward direction.

• The direction of the viscous force is always opposite to the direction of movement of an element.

• The main objective of this experiment was to measure the electric charge of the electron.

• Robert Millikan completed this experiment successfully.
