COMEDK · Physics · 3. Motion In One Dimension
The displacement-time graph of a moving particle is shown below
The instantaneous velocity of the particle is negative at the point
- A IV
- B I
- C II
- D III
Answer & Solution
Correct Answer
(D) III
Step-by-step Solution
Detailed explanation
The curve bending towards time axis represents decreasing velocity or negative velocity. So, at point III, the slope of the curve is negative. At this point, instantaneous velocity is negative.
