Electric Force and Electric Field problem

  1. Sep 29, 2011 #1
    1. The problem statement, all variables and given/known data

    A 0.15 g honeybee acquires a charge of 18 pC while flying. 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?
    What electric field strength and direction would allow the bee to hang suspended in the air?

    2. Relevant equations


    3. The attempt at a solution

    Weight of bee = 9.8 * .15g
    I honestly have no idea on how to begin this problem. I would appreciate any help!

    Do you know what "N/C" means? Do you know what the electric field is?
