A coil in the shape of an equilateral triangle of side l is suspended between the pole pieces of a permanent magnet such that \overrightarrow{B} is in plane of the coil. If due to a current i in the triangle a torque \tau acts on it, the side l of the triangle is (2005)

Correct Answer is : 2(τ√3Bi)1∕2

{2}/{\\sqrt{3}(\frac{\\tau }{B i} )

2({\\tau }/{\\sqrt{3} B i} )^{1 \/ 2}

{2}/{\\sqrt{3}(\frac{\\tau }{B i} )^{1 \/ 2}

{1}/{\\sqrt{3} \frac{\\tau }{B i}
