Question 22 POST_UTME_UNILAG • 2019 • PHYSICS • objective

A magnetic field of magnitude $B = 2.0 \times 10^{-2} , \text{T}$ is directed perp\endicular to the plane of a circular loop of radius $r = 0.05 , \text{m}$. The loop carries a current $I = 5.0 , \text{A}$. What is the magnitude of the torque experienced by the loop?

Answer Options

A. \( 1.25 \times 10^{-4} , \text{N} cdot \text{m} \)
B. \( 2.50 \times 10^{-4} , \text{N} cdot \text{m} \)
Correct Answer C. \( 5.00 \times 10^{-4} , \text{N} cdot \text{m} \)
D. \( 1.00 \times 10^{-3} , \text{N} cdot \text{m} \)
Correct Answer
C
Correct Option:
\( 5.00 \times 10^{-4} , \text{N} cdot \text{m} \)
