A conducting wire of length `l` and mass `m` is placed on two inclined rails as shown in figure. A current `I` is flowig in the wire in the direction shown When no magnetic field is present in the region, the wire is just on the verge of sliding. When a vertically upward magnetic field is switched on, the wire starts moving up the incline. The distance travelled by the wire as a function of time `t` will be
