1. A force of 14 N exists on charge q, which is 2.1E-9 C. What is the magnitude of the electric field?(adsbygoogle = window.adsbygoogle || []).push({});

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?
