Singly charged positive ions are kept on a circular orbit in a cyclotron. The magnetic field inside the cyclotron is 1.981 T. The mass of the ions is 3.67×10-26 kg, and speed of the ions is 2.75 percent of the speed of the light. What is the diameter of the orbit? (The speed of the light is 3.00×108 m/s.)(in m)

Respuesta :

Answer:

Therefore the diameter of the orbit is 1.91m

Explanation:

The path followed by the particle is a circle that keeps the relation given by

[tex]BVq=\frac{mv^2}{r}[/tex]

Re-arrange the equation for r,

[tex]r=\frac{mv}{Bq}[/tex]

From V is equal to speed of ions and there is a procent for this 'real speed' we have

[tex]V=\frac{2.75}{100} 3*10^8m/s[/tex]

[tex]V= 8.25*10^6m/s[/tex]

Replacing in the previous equation,

[tex]r= \frac{(3.67*10^{-26})(8.25*10^6)}{(1.981)(1.6*10^{-19})}[/tex]

[tex]r=0.955m[/tex]

[tex]D=r*2= 1.91m[/tex]

Therefore the diameter of the orbit is 1.91m
