Michelson-Morley experiment and its implications; Lorentz transformations-length contraction, time dilation, addition of relativistic velocities,
Questions:
Q 1. Two β-particles A and B emitted by a radioactive source R travel in opposite directions, each with a velocity of 0.9 c with respect to the source. Find the velocity of B with respect to A (Here c is the velocity of light).[15 marks]
Q 2. Calculate the percentage contraction in the length of a rod in a frame of reference, moving with velocity 0.8c in a direction (i) parallel to its length and (ii) at an angle of with its length. What is the orientation of the rod in the moving frame of reference in case (ii)? [20 marks]
