Hello.
A drop falling in air moves with terminal velocity (uniform velocity) when drag force balances its weight.
But when charged droplet moves in electric field (In Millikan's Oil drop Method when there is vaccume between two plates) it is suspended between two plates when electric force balances gravitational force.
Why this droplet does not suspends in air while both forces gravitational and drag are equal?
why it moves on with terminal velocity?
Why charged particle does not moves on in electric field when both forces (i.e electric and gravitational are equal)?
Please Answer...
