Find the rings radius

Reference no: EM13523718

The electric field on the axis of a uniformly charged ring has magnitude 400 kN/C at a point 6.4cm from the ring center. The magnitude 18cm from the center is 130kN/C ; in both cases the field points away from the ring.

(A) Find the ring's radius.

(B) Find the ring's charge.
