Answer:
The magnetic field strength is 3.9 x 10⁻³ T
Explanation:
The equation for the magnetic field strength produced by a long straight current-carrying wire is written as;
Where;
μ₀ is constant = 4π x 10⁻⁷ N/A
I is the maximum current = 20 A
r is the radius of the wire = 2.053/2 = 1.0265 mm = 1.0265 x 10⁻³ m
Substitute in this values into the equation above;
Therefore, the magnetic field strength is 3.9 x 10⁻³ T
When plane is flying along the wind then we can say
Now when its going against the wind the speed is given by
Now by the above two equations we will have
