(D) Given: Object distance $u = -30 \, cm$,Focal length $f = +30 \, cm$ (for a convex mirror).Using the mirror formula: $\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$Substituting the values: $\frac{1}{30} = \frac{1}{v} + \frac{1}{-30}$$\frac{1}{v} = \frac{1}{30} + \frac{1}{30} = \frac{2}{30} = \frac{1}{15}$Therefore,$v = +15 \, cm$.The positive sign indicates that the image is formed $15 \, cm$ behind the mirror.

$A$ point object is placed at a distance of $30 \, cm$ from a convex mirror of focal length $30 \, cm$. The image will form at
