QJEEM21Ph90fe: JEE Main 2021 Physics - Class 12 JEEM21Ph90fe Solution: A coil in the shape of an equilateral triangle of side 10 cm…

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 $$\sqrt{x}$$ $$\times$$ 10^$$-$$5 Nm. The value of x is .................
