Physics Question from JEE Main 2024 · 29 January, Shift 2

A horizontal straight wire 5 m5 \, \text{m} long extending from east to west falls freely at a right angle to the horizontal component of Earth’s magnetic field 0.60×10−4 Wb/m20.60 \times 10^{-4} \, \text{Wb/m}^2. The instantaneous value of emf induced in the wire when its velocity is 10 m/s10 \, \text{m/s} is:

  • A

    3×10−3 V3 \times 10^{-3} \, \text{V}

  • B

    6×10−3 V6 \times 10^{-3} \, \text{V}

  • C

    9×10−3 V9 \times 10^{-3} \, \text{V}

  • D

    2×10−3 V2 \times 10^{-3} \, \text{V}
