Answer to Problem 32A

Because length contracts for electrons when moving with the speed comparable with the light.

Explanation of Solution

Introduction: According to the length contraction phenomenon, the length of the moving objects looks shorter than actual to the stationary observers.

The actual linear accelerator at Stanford University in California is two-mile-long. But, for electrons which travel at speeds slightly less than the speed of light, the length contracts and for it, two-mile would look like a less than meter length only.

Conclusion: Thus, due to length contraction, two-mile linear accelerator looks like less than a meter long for electrons.
