Homework Help: Electric Fields

  1. Feb 16, 2010 #1
    1. The problem statement, all variables and given/known data

    A bird has gathered electrical charge of .0001C by rubbing against another bird(I have no idea why the bird is doing this but...) and it is flying to a certain point where there is a thunderstorm brewing and a vertical electrical field of 5000N/C. What is the electrical force on the bird.

    2. Relevant equations
    Pythagorean equation
    law of sines

    3. The attempt at a solution
    find the length of the third side of the triangle and use law of sines to find the angle of the force but I'm not sure if this is what it is asking for.

    Hello Lavas,

    I think you might be overthinking this one. If the charged bird is in a uniform electric field, then the electric force is simply the electric field strength times the charge (in the direction of the electric field).

    so simply .5 in the upwards direction
