SUMMARY
The charge of the oil drop is calculated to be -1μC using the equation E = σ / 2ε, resulting in an electric field (E) of 1000 N/C. The force balance equation ΣF = 0 leads to the conclusion that the electric force (Fel) equals the negative of the gravitational force (mg). The negative charge indicates that the direction of the electric force is towards the plate, while gravity acts downwards. The sign of gravity (g) is considered negative in this context.
