MCQ
Displacement time graph cannot be
  • A
    below the time axis.
  • straight line perpendicular to time axis as well as normal above and below the time axis.
  • C
    straight line parallel to time axis.
  • D
    inclined to the time axis.

Answer

Correct option: B.
straight line perpendicular to time axis as well as normal above and below the time axis.
(B)
The straight line normal to time axis will indicate multiple positions of a particle at one time, which is not possible.
