A particle accelerator has a circumference of 23 km. Inside it protons are accelerated to a speed of 0.999999972c. What is the circumference of the accelerator in the frame of reference of the protons?

Respuesta :

This is related to length contractive, so:

[tex]\begin{gathered} L=L_o\sqrt{1-\frac{v^2}{c^2}} \\ so: \\ L=23000\sqrt{1-(0.999999972)^2} \\ L\approx5.4m \end{gathered}[/tex]

Answer:

5.4 m
