A 1.5-m-long, 1.0-mm-diameter steel string is pulled by a 3.1 x 103 N tension force. By how much is the string stretched, in mm? The Young's modulus for steel is 20 x 1010 N/m². Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
