Use the following information to answer the next question.A light (approximately massless) frame supports a rectangular conducting wire WXYZ that isbalanced horizontally at its midpoint within a 2.0 T magnetic field created by a solenoid, asshown below. Sides WX and YZ are 10.0 cm long and are parallel to the magnetic field withinthe solenoid. Side XY is 3.5 cm long and is perpendicular to the magnetic field within thesolenoid. A 50-g mass hangs from the outside end of the massless frame.mNBWI= ?8) Determine magnitude of the current required through the rectangular conducting wire to keepthe system in horizontal equilibrium (stationary).
