A “cause” occurs at point 1 (x1, t1) and its “effect” occurs at point 2 (x2, t2). Use the Lorentz transformation to find t′2 − t′1, and showthat t′2 − t′1 > 0; that is, O′ can never see the “effect” coming before its “cause.

Consider a point charge q at rest, situated at the origin of some frame S. Its electric field, according to S is 9 E(,1) = 1 2/21 47€ 12 Of course, its magnetic field is zero. Now, you want to know what will happen to the fields if q moved to the right (positive x direction). Since it is at rest in the S frame, what you can do is go to another frame, S', then boost it to the negative x direction. This way, q moves to the right according to S'. Let the velocity of S'be v = -vi Solve for the magnetic field components as seen in the S' frame. Combine these to write down B'(x, t)

Please explain in detail An observer P stands on a train station platform as a high-speed train passes by at u/c = 0.8. The observer P, who measures the platform to be 60 m long, notices that the front and back ends of the train line up exactly with the ends of the platform at the same time. (a) How long does it take the train to pass P as he stands on the platform, as measured by his watch? (b) According to a rider T on the train, how long is the train? (c) According to a rider T on the train, what is the length of the train station platform?

The kinetic energy of a deuteron is twelve times greater than its rest energy. (The mass of a deuteron is 3.34 ✕ 10−27 kg) Determine its total energy in millions of electron volts, or MeV. Determine its speed, expressed as a multiple of the speed of light c, to the nearest 0.001c. (Round your answer to at least three decimal places.)
