Two plane mirror $M_{1}$ and $M_{2}$ are joined about there edges and then this structure is moving with velocity $v_{0}$ as shown in the figure. A point object $P$ is also moving with same speed $v_{0}$ in the direction shown in the figure. Determine the magnitude of the velocity of the image of $P$ in $M_{1}$ wrt image of $P$ in $M_{2}$ ?

Options:

Answer:

Solution:

Velocity of image of of the point in the first mirror with respect to the image of the point in the second mirror is

${({\vec{V}}_{I_{1}})}_{I_{2}} = - V_{0} \sqrt{3} \hat{i} - V_{0} \sqrt{3} \hat{j}$

$|{({\vec{V}}_{I_{1}})}_{I_{2}}| = V_{0} \sqrt{6}$
