Electric Field Video Lessons

Concept

# Problem: A 0.10 g honeybee acquires a charge of +23 pC while flying.a. The electric field near the surface of the earth is typically 100 N/C, directed downward. What is the ratio of the electric force on the bee to the bee's weight?b. What electric field strength and direction would allow the bee to hang suspended in the air?

###### FREE Expert Solution

The electric force on the honeybee:

$\overline{){{\mathbf{F}}}_{{\mathbf{e}}}{\mathbf{=}}{\mathbf{q}}{\mathbf{E}}}$

The weight of the honeybee:

$\overline{){{\mathbf{F}}}_{{\mathbf{g}}}{\mathbf{=}}{\mathbf{m}}{\mathbf{g}}}$

a.

Suppose the honeybee is suspended in a uniform electric field, the weight is equal to the electric force.
