Explanation:
Answer:
(a) 
(b) 1.3927 Nm
Explanation:
We have given that radius 
Current i = 2.34 A
Angle 
Uniform magnetic field B = 12.6 T
Area is given by 
(A) We know that magnetic dipole moment is given by 
, here i is current and A is area
So magnetic moment 
(b) We know that torque is given by
So torque experienced by coil will be
