"A straight wire that is 0.60 m long and carrying a current of 2.0 A, is placed at an angle with respect to a magnetic field of strength 0.30 T. Both the wire and the magnetic field lie on the same plane. The wire experiences a force of magnitude 0.14 N. Find the angle between the wire and the magnetic field. Give your answer in degrees as a two digit integer."
