Homework Help: Electric Field Question!

  1. Oct 26, 2012 #1
    1. The problem statement, all variables and given/known data
    A particle has a charge of -5.00 [itex]\mu[/itex]C. At a point near this particle, the electric field strength is 7.2 x 10^7 N/C. Determine the distance from this point to the charged particle.

    q = -5.00 x 10^-6 C
    E = 7.2 x 10^7 N/C
    k = 8.99 x 10^9 Nm^2/C^2

    2. Relevant equations
    E = kq / r^2


    3. The attempt at a solution

    r = (sqrt) (8.99 x 10^9 Nm^2/C^2)(5.00 x 10^-6) / (7.2 x 10^7 N/C)
    = 0.0249861073 m
