Two particles $A, B$ are moving on two concentric circles of radii $R_{1}$ and $R_{2}$ with equal angular speed $ω .$ At $t = 0,$ their positions and direction of motion are shown in the figure:

The relative velocity $\vec{V_{A}} - \vec{V_{B}}$ at $t = \frac{π}{2 ω}$ is given by:

Options:

Answer:

Solution:

$t = \frac{π}{2 ω}$

${\vec{V}}_{A} = ω R_{1} (- \hat{i})$

${\vec{V}}_{B} = ω R_{2} (- \hat{i})$

$\vec{V_{A}} - \vec{V_{B}} = ω (R_{2} - R_{1}) \hat{i}$
