Two particles \( A \) and \( B \) are moving in a straight line with the same speed. Which of the following statement(s) is/are correct for the relative motion of the two particles?
(a) The relative velocity \( v_{A B} \) or \( v_{B A} \) is zero, only if they are moving in the same direction.
(b) If the particles are moving in opposite direction, the magnitude of \( v_{B A} \) or \( v_{A B} \) is twice than the magnitude of velocity of \( A \) or that of \( B \).
(c) The relative velocity \( v_{A B} \) or \( v_{B A} \) is always zero.
(d) Both (a) and (b)
