Physics - Geometrical Optics Question with Solution | TestHub

Radius of curvature of a concave mirror varies as $R=\left|\frac{6}{t^2-5t+6}\right|\mathrm{cm}$. Initially the object was at a distance 100 cm from the pole as shown. At $\mathrm{t}=0$ the object started moving with velocity $\mathrm{v}=2\hat{\mathrm{t}}\hat{\mathrm{i}}(\mathrm{cm}/\mathrm{s})$. Find the speed of image at time $\mathrm{t}=3\sec$. Mirror is moving with constant velocity $(-3\hat{\mathrm{i}})$.
