Answer:
So length of the tube in electron reference frame is 0.7348 m
Explanation:
We have given total length of the tube [tex]L_V=3.2km=3200m[/tex]
Velocity of electron v = 0.99999997c ,here c is the velocity of light
We have to find the length of the tube in electron reference frame
Length of the tube in electron reference frame is given by [tex]L=L_V\sqrt{1-\frac{v^2}{c^2}}=3200\times \sqrt{1-\frac{(0.99999997c)^2}{c^2}}=1.431m[/tex]
So length of the tube in electron reference frame is 0.7348 m
