Two metal strips, each of length 2m, are clamped parallel to each other on a horizontal floor with a separation 1m between them. A wire of mass m lies on them perpendicularly as shown in figure. A vertically upward magnetic field of strength B exists in the space. The metal strips are smooth but the coefficient of friction between the wire and the floor is\[\mu \]. A current i is established when the switch S is closed at the instant\[t=0\]. How far (in meter) away from the strips will the wire reach? (assume \[i=\]constant) \[(i=2amp.=0.2,\text{ }m=1kg,\text{ }B=1T)\]
