What single change to the experimental system would reduce the electric field strength necessary to maintain the oil drop in static equilibrium? ANS- Decreasing the mass of the drop -When the oil drop (with charge -q) is in static eqbm, the electric force it feels, qE upward, is balanced by the gravitational force, mg downward. Thus, qE = mg, so E = mg / q. Don't be confused by the electric field strength in a capacitor, E = V / d. Which of the following equations gives the voltage V ...
