question

In a particular inertial reference frame S, two events occur a distance 6 × 10^8 m apart and are separated by a time inter-val of (a) 2 sec (b) 1 sec. What is the proper time interval between these two events?

category

physics

options

  1. ∆t' = 2
  2. ∆t' = 2.5 sec
  3. ∆t' cannot be determined without additional information about the velocity of S' relative to S
  4. ∆t' = 4 sec
  5. ∆t' = √3 sec
  6. The two events never occur at the same place
  7. ∆t' = 0 and no reference frame S' can be found
  8. ∆t' = 3 sec
  9. ∆t' = 1.5 sec
  10. ∆t' = 1
