# Let it go

A rectangular loop with a sliding connector of length "1 m" is situated in a uniform magnetic field of "2 T" perpendicular to the plane of loop. Resistance of connector is 2 $$\Omega$$. Two resistances of 6 $$\Omega$$ and 3 $$\Omega$$ are connected as shown in the figure. The external force required to keep the connector moving with a constant velocity $$2 \frac { m }{ s }$$ is $$\text{___________}$$.
