The speed of air at the intake area is (m/s).
<h3 /><h3>Continuity equation</h3>
The continuity equation is used to determine the flow rate at different sections of a pipe or fluid conduit.
The continuity equation is given as;
- Let the intake area = A₁
- Let the velocity of air in intake area = v₁
- Let the area of the test section = A₂
- Velocity of air in test section, v₂ = 10 m/s
The speed of air at the intake area is calculated as follows;

The Lorentz force exerted on the particle due to the magnetic field provides the centripetal force that keeps the particle in circular motion:
where
m is the particle mass
v is its velocity
r its orbital radius
q its charge
B the magnetic field intensity
and where we neglected the factor
in the Lorentz force formula because the particle is traveling perpendicular to the magnetic field, so
.
Re-arranging the formula, we get
(1)
The problem gives us all the data about the particle and the magnetic field:
(we are only interested in the magnitude of the charge)
And by plugging these numbers into eq.(1), we find the radius of the orbit
