JEE Advanced 2023 Physics question on Electromagnetic Induction and AC

A rectangular conducting loop of length 4 cm and width 2 cm is in the xyxy-plane, as shown in the figure. It is being moved away from a thin and long conducting wire along the direction 32 x^+12 y^\dfrac{\sqrt{3}}{2}\,\hat{x} + \dfrac{1}{2}\,\hat{y} with a constant speed v. The wire is carrying a steady current I=10I = 10 A in the positive xx-direction. A current of 10 μ\muA flows through the loop when it is at a distance d=4d = 4 cm from the wire. If the resistance of the loop is 0.1 Ω\Omega, then the value of v is ________ m s−1^{-1}.

[Given: The permeability of free space μ0=4π×10−7\mu_0 = 4\pi \times 10^{-7} N A−2^{-2}]
