A rough inclined plane inclined at angle of `37^(@)` with horizontal has a metallic wire of length `20cm` with its length `_|_` to length of inclines plane `(mu=0.1)` When a current of its passingthrough the wire and a magnetic field is applied normal to the plane upwards, the wire starts moving up with uniform velocity for `B=0.5T`. The find the magnitude of current `i,(` mass of the wire `=50g)`
