A butterfly is sitting on a wire of length 2.6 m. The combined mass of the butterfly and the wire is 114 g. A magnetic field of strength of 4.0 T is applied in the region perpendicular to the wire. A current flows through the wire as such that the force due to the magnetic field balances the weight of the butterfly and the wire. What is the magnitude of the current (in A)? Round off to TWO decimal places [Hint: equate the magnetic force on the wire and the total weight of the butterfly and the wire]
