The attractive electrostatic force between the point charges 8.12×10−6C and Q has a magnitude of 0.670N when the separation between the charges is 7.26m.
Find the sign and magnitude of the charge Q.
(this is a direct cut and paste)
The Attempt at a Solution
8.12×10−6C = (k(|q1||q2|)/(7.26m^2))
(8.12×10−6C * 7.26m^2)/(k) = (|q1||q2|)
I'm really getting stuck here, and largely because I feel like the problem reads strangely. I feel like I'm headed in the wrong direction but if they give me Q in the beginning what am I finding? If the problem doesn't read strangely I'll keep working on it sans help.
