A plane mirror is placed at the origin parallel to $y$ -axis, facing the positive $x$ -axis. An object starts from $(2 m, 0,$, 0) with a velocity of $(2 \hat{i}+2 \hat{j}) \mathrm{m} / \mathrm{s}$. The relative velocity of image with respect to object is along (a) positive $x$ -axis (b) negative $x$ -axis (c) positive $y$ -axis (d) negative $y$ -axis
A point object is placed at O. A plane mirror placed parallel to $y$ -axis is at rest at $\mathrm{x}=\mathrm{x}_{0}$ at $\mathrm{t}=0$ has acceleration $\overrightarrow{\mathrm{a}}=\mathrm{a} \hat{\mathrm{i}}$. The velocity of the image of the object $\mathrm{O}$, in the plane mirror at time $\mathrm{t}=\frac{\mathrm{x}_{0}}{\mathrm{a}}$ is: (a) $2 x_{0}$ (b) $x_{0}$ (c) $\frac{x_{0}}{2}$ (d) $\frac{x_{0}}{4}$
Two plane mirrors are inclined at $90^{\circ}$. An object is placed between them whose coordinates are $(a, b)$. Find the position vectors of all the images formed : (Take $\ddot{\mathbf{i}}, \overrightarrow{\mathbf{j}}$ are unit vectors along $x-y$ axis) (a) $-a \hat{\mathbf{i}}-b \hat{\mathbf{j}}, a \hat{\mathbf{i}}-b \hat{\mathbf{j}},-a \hat{\mathbf{i}}+b \hat{\mathbf{j}}$(b) $-a \hat{\mathbf{i}}+b \hat{\mathbf{j}},-a \hat{\mathbf{i}}-b \hat{\mathbf{j}}, a \hat{\mathbf{i}}-b \hat{\mathbf{j}}$ (c) $a \hat{\mathbf{i}}+b \hat{\mathbf{j}},-a \hat{\mathbf{i}}-b \hat{\mathbf{j}},+a \hat{\mathbf{i}}-b \hat{\mathbf{j}}$ (d) none of the above
