Q.A wire of length $l$ carrying a current $I$ along the Y direction is kept in a magnetic field $\vec B = \beta(\hat i + 3\hat j + \hat k)$ T. The magnitude of the Lorentz force acting on the wire is [the four answer options in the source scan show a coefficient layout (with the square
-root symbol apparently dropped by the OCR in at least one option) that could not be verbatim-transcribed with confidence -- held rather than guessed]
