Magnitude of an electric field

  1. Mar 1, 2012 #1
    1. A force of 14 N exists on charge q, which is 2.1E-9 C. What is the magnitude of the electric field?



    2. Relevant equation is E=Kq'/r^2



    3. I attempted using the equation above but the question doesn't include any distance. Is there another equation I should use?

    Can you use E = F/q?
