Physics · JEE Main · NTA Exams — Kinematics
The position vector of a particle is:
\(\vec{r}=a \cos \alpha t \hat{i}+a \sin \omega t \hat{j}\)
The velocity of the particle is:
\(\vec{r}=a \cos \alpha t \hat{i}+a \sin \omega t \hat{j}\)
The velocity of the particle is:
- parallel to position vector
- perpendicular to position vector
- directed towards origin
- directed away from the origin
Answer
(B) perpendicular to position vector
