A conducting square loop
of side L, mass M and resistance R is moving in the XY plane with its edges parallel to the X and Y axes. The region y ≥ 0 has a uniform magnetic field, 
The magnetic field is zero everywhere else. At time t = 0, the loop starts to enter the magnetic field with an initial velocity \(v_{0} \ ilde{j} \mathrm{~m} / \mathrm{s} .\) as shown in the figure. Considering the quantity \(K=\frac{B_{0}^{2} L^{2}}{R M}\)in appropriate units, ignoring self-inductance of the loop and gravity, which of the following statements is/are correct?
