### Problem StatementA rectangular loop of wire of width 10 cm and length 20 cm has a current of 2.5 A flowing through it. Two sides of the loop are oriented parallel to a uniform magnetic field of strength 0.037 T, with the other two sides being perpendicular to the magnetic field. The magnitude of the torque on the loop is:#### OptionsA) 0.025 m⋅N B) 0.0093 m⋅N C) 0.038 m⋅N D) 0.0019 m⋅N E) 0.050 m⋅N ### ExplanationTo solve for the torque on a rectangular loop in a magnetic field, the equation used is:\[ \tau = n \cdot I \cdot A \cdot B \cdot \sin(\theta) \]Where:- \( \tau \) is the torque,- \( n \) is the number of loops (1 in this case),- \( I \) is the current (2.5 A),- \( A \) is the area of the loop,- \( B \) is the magnetic field strength (0.037 T),- \( \theta \) is the angle between the normal to the plane of the loop and the magnetic field (90 degrees here, so \(\sin(90^\circ) = 1\)).Given the width = 10 cm = 0.1 m and the length = 20 cm = 0.2 m, the area \( A \) becomes \( 0.1 \times 0.2 = 0.02 \, \text{m}^2 \).Plug these values into the formula to find the torque.
