What is the Magnitude of the Electric Field?

[Covert Liason]

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?

Yea I just realized that soon after. Thank you for the quick reply anyway

No problem!
