Mathematically, the electric field measured at a point is defined as: O the force experienced by a test charge at the point per unit test charge; O the value of the test charge per unit force being experienced by the test charge; O the force experienced by a source charge at the point per unit source charge; the value of the source charge per unit force being experienced by the source charge;

Flying insects such as bees may accumulate a small positive electric charge as they fly. In one experiment, the mean electric charge of 50 bees was measured to be ++(30 ±± 5) pCpC per bee. Researchers also observed the electrical properties of a plant consisting of a flower atop a long stem. The charge on the stem was measured as a positively charged bee approached, landed, and flew away. Plants are normally electrically neutral, so the measured net electric charge on the stem was zero when the bee was very far away. As the bee approached the flower, a small net positive charge was detected in the stem, even before the bee landed. Once the bee landed, the whole plant became positively charged, and this positive charge remained on the plant after the bee flew away. By creating artificial flowers with various charge values, experimenters found that bees can distinguish between charged and uncharged flowers and may use the positive electric charge left by a previous bee as a cue…

The "Millikan oil drop" experiment identified the electron as the fundamental unit of electric charge, possessing a charge of -1.6 x 1019 Coulombs. Millikan accomplished this calculation by spritzing charged oil drops into a chamber, permitting them to fall under gravity, and then turning on an electric field in the direction opposite gravity and observing that some drops stopped falling and hovered in mid-air. Why did these drops hover in midair? Answer in terms of an equation involving Newton's second law (F = ma).

Suppose a capacitor consists of two coaxial thin cylindrical conductors. The inner cylinder of radius ra has a charge of +Q, while the outer cylinder of radius rp has charge -Q. The electric field E at a radial distance r from the central axis is given by the function: E = aer/ao + B/r + bo %| where alpha (a), beta (B), ao and bo are constants. Find an expression for its capacitance. First, let us derive the potential difference Vab between the two conductors. The potential difference is related to the electric field by: Va Edr= Edr Calculating the antiderivative or indefinite integral, Vab = (-aaoe-r/ao + B + bo By definition, the capacitance C is related to the charge and potential difference by: C = Evaluating with the upper and lower limits of integration for Vab, then simplifying: C = Q/( (e-"b/ao - era/ao) + B In( ) + bo ( ))
