Q.6 In an intertial frame S, a stationary rod makes an angle 0 with the x-axis. Another interial frame S moves with a velocity v with respect to S along the common x-x axis. As observed from S the angle made by the rod with the x'-axis is 0'. Which of the following statement is corect? (a) 0<0 (b) 0'> 0 (c) 0<0ifv is negative and 6'> 0if v is positive (d) 0'>0ifv is negative and 0'<0 ifv is positive
