A 50 turn circular coil of radius 2cm carrying a current of 5.0 A is rotated in a magnetic field of strength 0.20T. In a particular position of the coil. The torque acting is half of the maximum torque. The angle between the magnetic field and the plane of the coil is

According to me the values of B ,n,I,r are of no use as in the question it is clearly written that the value of the torque is Half of the maximum value
Torque=MBsin theta
Sin theta is Max when it's value is 1
Sin 90 = 1
Torque=MB
Half of the max value 1/2
Sin 30 =1/2
Torque''= MB/2
Torque" = Torque/2
Angle= 30 °
I hope it helps(θ‿θ)
