Physics Question from JEE Main 2023 · 11 April, Shift 1

The magnetic field BB crossing normally a square metallic plate of area 4 m24 \, \text{m}^2 increases linearly with time from zero, reaching 2 mT2 \, \text{mT} at t=1 st = 1 \, \text{s}, 4 mT4 \, \text{mT} at t=2 st = 2 \, \text{s}, 8 mT8 \, \text{mT} at t=4 st = 4 \, \text{s} and 10 mT10 \, \text{mT} at t=5 st = 5 \, \text{s}. The magnitude of induced emf in the plate during t=2 st = 2 \, \text{s} to t=4 st = 4 \, \text{s} is _____ mV.

  • A

    8 mV8 \, \text{mV}

  • B
