Charges: What are the values of the distance l and the charge q?

Two charges, each with a value of +q are separated by a distance of l m. The resultant electric field and the potential measured at a point P a distance l/3 m from the left charge, are, 10 N/C and 2 V, respectively. What are the values of the distance l and the charge q?
