MCQ
Which of the following statements regarding motion of particle is true ?
  • A
    The motion between $A$ and $B$ is known.
  • B
    The motion between $A$ and $B$ is erratic.
  • ✓
    The motion between $A$ and $B$ may have been steady or erratic.
  • D
    The motion between $A$ and $B$ is steady.
✓

Answer

Correct option: C.
The motion between $A$ and $B$ may have been steady or erratic.
$c. $ The motion between $A$ and $B$ may have been steady or erratic.
Explanation:
The motion between $A$ and $B$ is steady if the velocity of the particle is constant and erratic if it is variable. From the question it is not clear what happens with the particle during the motion so we cannot say whether the particle is in erratic or steady motion.
