1. The problem statement, all variables and given/known data Suppose a circle of radius 'b' is set in motion.Calculate the relativistic speed parameter β(=v/c) such that the circle is seen as an ellipse of semiminor axis 'a' and semimajor axis 'b' where a <b.3 marks. 2. Relevant equations L=L0/γ 3. The attempt at a solution Whichever direction the circle travels say x-axis the radius shrinks in that direction to 'a'. So a=b/γ. (a/b)2=1-(v/c)2 β=√[1-(a/b)2] Is my deduction correct? Do I need to show more mathematics here or to say is my above workout enough?
