Solving a problem in physics section 10 paragraph 5 e

5. As long straight wire carrying a current. Near the wire is square frame made of thin wire resistance R = 0,02 Ohm. The wire lies in a plane parallel to the frame and its two sides, the distance to which the wires are respectively of a1 = 10 cm, a2 = 20 cm. Find the current in the wire, if it is turned on through the frame elapsed amount of electricity q = 693 SCLC.
