A rectangular conducting loop of length 4 cm4 \mathrm{~cm}4 cm and width 2 cm2 \mathrm{~cm}2 cm is in the xyx yxy-plane, as shown in the figure. It is being moved away from a thin and long conducting wire along the direction 32x^+12y^\frac{\sqrt{3}}{2} \hat{x}+\frac{1}{2} \hat{y}23​​x^+21​y^​ with a constant speed v\mathrm{v}v. The wire is carrying a steady current I=10 AI=10 \mathrm{~A}I=10 A in the positive xxx-direction. A current of 10μA10 \mu \mathrm{A}10μA flows through the loop when it is at a distance d=4 cmd=4 \mathrm{~cm}d=4 cm from the wire. If the resistance of the loop is 0.1Ω0.1 \Omega0.1Ω, then the value of v\mathrm{v}v is ‾\underline{\hspace{2cm}}​ms−1\mathrm{m} \mathrm{s}^{-1}ms−1.
