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 ...

WGU C451 Module 2: Forces, Energy, and Motion Questions and Answers Rated A+ What is potential energy? Stored energy that has the potential to do work. How does a change in mass of an object affect the gravitational potential energy of that object? How does a change in height affect it? The greater the mass, the greater the force of gravity it exerts, so the more attracted to each other they will be. When objects are pulled further apart, the force of gravity weakens. The distance increases the...
