JEE Main & Advanced Physics Two Dimensional Motion Question Bank Assertion and Reason

  • question_answer
                Assertion          :           In order to hit a target, a man should point his rifle in the same direction as target.             Reason            :           The horizontal range of the bullet is dependent on the angle of projectile with horizontal direction.          

    A)             If both assertion and reason are true and the reason is the correct explanation of the assertion.            

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.            

    C)             If assertion is true but reason is false.            

    D)             If the assertion and reason both are false.            

    E)             If assertion is false but reason is true.            

    Correct Answer: E

    Solution :

                    The man should point his rifle at a point higher than the target since the bullet suffers a vertically downward deflection \[\left( y=\frac{1}{2}g{{t}^{2}} \right)\] due to gravity.
