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 place 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-

Correct Answer is : 2(τ√3Bi)12

{2}/{\sqrt{3}} (\frac{\tau}{ {\Bi}})

{1}/{\sqrt{3}} \frac{\tau}{ {\B}_1}

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

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