The resistance of an electrical circuit is jointly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire. If a wire with a length of 5 meters and a cross-sectional area of 2 square millimeters has a resistance of 10 ohms, what will be the resistance of a wire with a length of 8 meters and a cross-sectional area of 3 square millimeters?
