Question

If the displacement of a particle and corresponding time be plotted along y and x axes respectively, then which of the following statements is (are) correct?

• A. The curve may lie in fourth quadrant.
• B. The curve may drop as time passes.
  
• C. The curve may exhibit peaks corresponding to maxima.
• D. All of the above.

Answer 1

Answer: (D)

All of the above.

Displacement can be negative but the time can not be negative. So, according to this condition, the graph can only lie in the first and fourth quadrants, where the time is positive. According to the position of the particle from the starting point, there can be corresponding maxima and the curve can drop. But, the curve stays in the first and fourth quadrant only.
