AIIMS 2019 Physics Magnetic Field and Force MCQ Question

The force per unit length $F/dl$ at point P is calculated using the formula $F/dl = iB$, where $i$ is the current and $B$ is the magnetic field. Substituting the values, $i = 5 \, \text{A}$ and $B = 2 \times 10^{-5} \, \text{T}$, results in $F/dl = 5 \times 2 \times 10^{-5} = 10^{-4} \, \text{N/m}$. However, the question states the final answer should be $2 \times 10^{-5} \, \text{N/m}$ based on the magnetic field calculation, indicating a potential misinterpretation of the values or context. Other options are incorrect as they do not match the calculated force per unit length based on the given parameters.
