  • question_answer
    In the given figure, two cars coming from town P are traveling with a speed of\[65\text{ }km\text{ }{{h}^{-1}}\]. When they reach the cross road, one of the car turns towards town Q whereas the other continues forward towards town R. Both continue to move with the same speed of \[65\text{ }km\text{ }{{h}^{-1}}\].
     
     Which of the following options is correct for given statements?
    (i) Both cars have same velocities even if the car turns towards town 0.
    (ii) Two bodies have same velocities if they are moving with same speed in different directions,
     

    A) Both (i) and (ii) are correct and (ii) is the correct explanation of (i).   

    B) Both (i) and (ii) are correct but (ii) is not the correct explanation of (i).          

    C) Only (i) is correct.       

    D) Neither (i) nor (ii) is correct.   

    Correct Answer: D

    Solution :

    Both cars have same speed but not same velocities as they are moving in different directions. If two bodies have same velocity then they have same speed in the same direction,
