Question

The motion of a moving body is plotted along the path OABC.
What is wrong in the graph?

• A. Body has two displacements between 0 to 5 seconds.
• B. Body has two displacements between 5 to 10 seconds.
• C. Body has two displacements between 10 to 15 seconds.
• D. Time is negative.

Answer 1

The correct option is C Body has two displacements between 10 to 15 seconds.

Between 10 to 15 seconds, the body has two positions, which is not possible because it cannot be in two places at once. Also, in the last part of motion from B to C, it seems that time runs backwards, which is again not possible.
