Assertion: For a particle moving along a straight line or in a plane, the average velocity vector over a time interval can be equal to instantaneous velocity at the end of the interval, even if velocity of particle is not constant.
Reason: \(\frac{\overrightarrow{\mathrm{t}}_{2}-\overrightarrow{\mathrm{t}}_{1}}{\mathrm{t}_{2}-\mathrm{t}_{1}}=\frac{\mathrm{d} \overrightarrow{\mathrm{r}}}{\mathrm{dt}}\)
Reason: \(\frac{\overrightarrow{\mathrm{t}}_{2}-\overrightarrow{\mathrm{t}}_{1}}{\mathrm{t}_{2}-\mathrm{t}_{1}}=\frac{\mathrm{d} \overrightarrow{\mathrm{r}}}{\mathrm{dt}}\)
- If both Assertion and reason are true and reason is the correct explanation of the assertion.
- If both assertion and reason are true but reason is not the correct explanation of the assertion.
- If assertion is true but reason is false.
- If assertion is false but reason is true.
Answer
(C) If assertion is true but reason is false.
