Electromagnetic Induction

A square loop of side \(10 \mathrm{~cm}\) and resistance \(0.7 \Omega\) is placed vertically in east-west plane. A uniform magnetic field of \(0.20 T\) 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 __________.
