Answer:
8-5=3
The bigger force is to the left
3N to the left
Explanation:
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

Answer:
It’s D
Explanation:
Because I took the USA test prep and got it right
1 angstrom = 10^-13 km
500 angstrom = 500 x 10^-13 km = 5 x 10^-11
