Q151 / 160 · TS EAMCET 2022 (19 Jul Shift 2) · Physics
The magnetic flux through the triangular loop shown in the figure below:
where a uniform magnetic field of strength $2 \mathrm{~T}$ points perpendicularly into the plane of the triangle.
where a uniform magnetic field of strength $2 \mathrm{~T}$ points perpendicularly into the plane of the triangle.
- A$10^{-4} \mathrm{~Wb}$
- Correct answerB$2 \times 10^{-4} \mathrm{~Wb}$
- C$1 \mathrm{~Wb}$
- D$2 \mathrm{~Wb}$
Solution
$\begin{aligned} & \phi=\overrightarrow{\mathrm{B}} \cdot \overrightarrow{\mathrm{A}} \\ & =\mathrm{BA} \cos 0^{\circ} \\ & =2 \times \frac{1}{2} \times 2 \times 1 \times 10^{-4} \\ & =2 \times 10^{-4} \mathrm{~Wb}\end{aligned}$
Hence, the correct answer is option: 'B'.
