I need help with this question.

This answer has no units (degrees) m KE 5 m/5 m/5*2 N W N/m kg.m/s or N-5 N/m^2 or Pa kg/m* 3 E m/5*3 timesIn the figure, two concentric circular loops of wire carrying current in the same direction lie in the same plane. Loop 1 has radius 1.70 cm and carries 4.00 mA. Loop 2 has radius 2.80 cm and carries 5.70 mA. Loop 2 is to be rotated about a diameter while the net magnetic field B set up by the two loops at their common center is measured. Through what angle must loop 2 be rotated so that the magnitude of the net field is 95.0 nT? Number i 95.0 Units v
