   1. A.If $v_0=1.5KL$, the loop will stop before it enters completely inside the region of magnetic field.
   2. B.When the complete loop is inside the region of magnetic field, the net force acting on the loop is zero.
   3. C.If $v_0=\frac{KL}{10}$, the loop comes to rest at $t=\left(\frac{1}{K}\right)\ln \left(\frac{5}{2}\right)$.
   4. D.If $v_0=3KL$, the complete loop enters inside the region of magnetic field at time $t=\left(\frac{1}{K}\right)\ln \left(\frac{3}{2}\right)$.
