1. The problem statement, all variables and given/known data Two 10-cm-diameter charged rings face each other, 25cm apart. The left ring is charged to -17nC and the right ring is charged to +17nC . A.What is the magnitude of the electric field E⃗ at the midpoint between the two rings? B.What is the magnitude of the force F⃗ on a -1.0 nC charge placed at the midpoint? Express your answer to two significant figures and include the appropriate units. 2. Relevant equations (E1)z=ZQ1/4πε0(z^2+r^2)^(3/2) 3. The attempt at a solution ((9E9)(.10)(-17E-9))/((.10)^2+(.50)^2)^3/2= 2.2E4. Unfortunately this is not the answer any help?
