A coil in the shape of an equilateral triangle of side l is suspended between the pole pieces of a permanent magnet such that`vec B ` is in the 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

A coil in the shape of an equilateral triangle of side l is suspended between the pole pieces of permanent magnet. Such that vecB 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 triangel is:

Perimeter of equilateral triangle with side 2l is 6l

A coil in the shape of an equilateral triangle of side 10 cm lies in a vertical plane between the pole pieces of permanent magnet producing a horizontal magnetic field 20 mT. The torque acting on the coil when a current of 0.2 A is passed through it and its plane becomes parallel to the magnetic field will be sqrtx xx 10^(- 5) Nm . The value of x is ____
