    High School What is the fact of constant of proportionality?

    Its so confusing for me... in Ohm's law V=IR here V is independent variable and I is dependent variable (i,e increasing V, I also increases) here we place R (proportionality constant) with I (dependent variable). On the other hand.. in electrostatic force F=k(Qq/r^2 ) here K is constant...

    Undergrad Droplet's motion in electric field and gravitational field?

    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...
