Question

The displacement-time graph of a moving particle is shown below. The instantaneous velocity of the particle is negative at the point

• A. E
• B. F
• C. C
• D. D

Answer 1

Answer: (A)

E

Answer 2

The slope of the tangent at any point on the displacement-time graph gives instantaneous velocity at that instant. In the given graph, the slope is negative at point $E$.

The velocity (v)$=\frac{ds}{dt}$.
Therefore, instantaneous velocity at point E is negative.
