QJEEM24Ph22bc: JEE Main 2024 Physics - Class 12 JEEM24Ph22bc Solution: A square loop of side 10   cm and resistance 0.7 Ω is…

A square loop of side $$10\mathrm{cm}$$ and resistance $$0.7\mathrm{\Omega }$$ is placed vertically in east-west plane. A uniform magnetic field of $$0.20T$$ is set up across the plane in north east direction. The magnetic field is decreased to zero in $$1\mathrm{s}$$ at a steady rate. Then, magnitude of induced emf is $$\sqrt{x}\times {10}^{-3}\mathrm{V}$$. The value of $$x$$ is __________.
