  • question_answer
    The velocity versus time graph of a body in motion is shown below. The displacement of the body will be

    A) 20 m                                        

    B) 60 m

    C) 80 m            

    D) 110 m

    Correct Answer: C

    Solution :

    [c] The area under velocity-time graph gives the value of displacement of the body, i.e. Displacement = Area of trapezium OBCDO
    \[=\frac{1}{2}\times (6+10)\times 10\]
    = 5 \[\times\]16 = 80 m
