Uniform Electric Field

  1. Jan 18, 2007 #1
    1. The problem statement, all variables and given/known data

    In a uniform electric field, a proton has a

    a. constant velocity in the direction of the field.
    b. constant velocity in the opposite direction of the electric field.
    c. constant acceleration in the direction of the electric field.
    d. constant acceleration in a direction opposite the electric field.
    e. constant acceleration in a direction perpendicular to the electric


    2. Relevant equations

    Possibly vector E = m*a/q

    3. The attempt at a solution

    Is the correct answer c. constant acceleration in the direction of the electric field?

    A uniform electric field has the same magnitude and direction throughout the region. Wouldn't the proton then have a constant acceleration, and the direction of the acceleration (also force?) would be in the field's same direction since the charge is positive?

    Thanks.

    Your logic seems to be correct.
