Let \(\overline{\mathrm{v}} \text { and } \overline{\mathrm{a}}\) denote the velocity and acceleration respectively of a particle moving in a circular path then,
- \(\tilde{\mathrm{v}} . \overline{\mathrm{a}}<0\) all the time
- \(\vec{v} . \bar{a}>0\)all the time
- \(\vec{v} \cdot \vec{a}=0\)all the time
- (a ),(b ) & (c ) all are possible depending upon the direction of net acceleration.
Answer
(D) (a ),(b ) & (c ) all are possible depending upon the direction of net acceleration.
