Answer:
Torque, 
Explanation:
Given that,
The number of turns in the coil, N = 47.5
Radius of the coil, r = 5.25 cm
Uniform magnetic field, B = 0.535 T
Current in the coil, I = 26.9 mA
The magnitude of the maximum possible torque exerted on the coil isg given by :

So, the magnitude of the maximum possible torque exerted on the coil is
.
<u>Answer</u>
2.06977 seconds
<u>Explanation</u>
Acceleration, a, is the rate of change of velocity
a = (v-u)/t
where v and u are final and initial velocities respectively.
4.3 = (16.0 - 7.1)/t
4.3 = 8.9/t
t = 8.9/4.3
= 2.06977 seconds
