Answer:
The magnetic field in the region a < r < b is
Explanation:
If we have the a < r < b. The formula of current is:
Where:
A = area enclosed by the loop.
Itotal = total current in loop.

<em>Explanation: </em>let s = speed at launch
v = 0 at top = s sin 63 - g t
so at top
t = s sin 63/g = .0909 s
h = 13.6 = s sin 63 t - 4.9 t^2
13.6 = .081s^2 - .0405 s^2
s^2 = 336
s = 18.3 m/s
