Vedclass · Answer

(A) Given: Object distance $u = -15\, cm$, Radius of curvature $R = +60\, cm$.Focal length $f = R / 2 = +60 / 2 = +30\, cm$.Using the mirror formula: $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$.Substituting the values: $\frac{1}{v} + \frac{1}{-15} = \frac{1}{30}$.$\frac{1}{v} = \frac{1}{30} + \frac{1}{15} = \frac{1 + 2}{30} = \frac{3}{30} = \frac{1}{10}$.Therefore, $v = +10\, cm$.Magnification $m = -\frac{v}{u} = -\frac{10}{-15} = \frac{2}{3} \approx 0.67$.The image is virtual, erect, and diminished.

An object is placed $15\, cm$ from a convex mirror of radius of curvature $60\, cm$. Find the position of the image and its magnification.
