A conducting rod of length `'l'=2sqrt(5)` meter and mass `'m'=4kg` lies on the horizontal table. Coefficient of friction between the rod and the table is `'mu'=(1/2)`. If the current in the conductor si 2 ampere, then find the minimum magnitude of magnetic field strength (in Tesla) such that conducting rod just starts to translate along `x` -axis (take `g=10m//sec^(2)`) [neglect the radius of rod]
