Two 10-cm-diameter charged rings face each other, 20cm apart. The left ring is charged to -22nC and the right ring is charged to +22nC .
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?
