D) of the combined effect of all the three factors stated in [a], [b] and [c]
Correct Answer: B
Solution :
All options are correct : (i) When two bodies A & B move in opposite directions then relative velocity between A & B either \[{{V}_{AB}}\] or \[{{V}_{BA}}\] both are greater than \[{{V}_{A}}\] & \[{{V}_{B}}\]. (ii) When two bodies A & B move in parallel direction then \[{{V}_{AB}}={{V}_{A}}-{{V}_{B}}\Rightarrow {{V}_{AB}}<{{V}_{A}}\] \[{{V}_{BA}}={{V}_{B}}-{{V}_{A}}\Rightarrow {{V}_{BA}}<{{V}_{B}}\]
