Answer:
B = 8.0487mT
Explanation:
To solve the exercise it is necessary to take into account the considerations of the Magnetic Force described by Faraday,
The magnetic force is given by the formula

Where,
B = Magnetic Field
I = Current
L = Length
Angle between the magnetic field and the velocity, for this case are perpendicular, then is 90 degrees
According to our data we have that
I = 16.4A
F = 0.132N/m
As we know our equation must be modificated to Force per length unit, that is

Replacing the values we have that

Solving for B,


Answer:
20.88 m/s
Explanation:
Curve A:
theta = 12.7, vA = 19.1 m/s
Curve B:
Theta = 15.1 degree
Let the speed is v.
By the use of given formula
tanθ = v^2 / rg
For Curve A
tan 12.7 = (19.1)^2 / r g ...... (1)
For Curve B
tan 15.1 = v^2 / r g ......(2)
Divide equation (2) by equation (1), we get
tan 15.1 / tan 12.7 = v^2 / (19.1)^2
0.269 / 0.225 = v^2 / 364.81
v = 20.88 m/s
