An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image. |

Answer» Solution :As per SIGN convention f = + 15 CM and u = - 10 cm. As `(1)/(f) = (1)/(v) + (1)/(u) rArr (1)/(+15)= (1)/(v) + (1)/((-10)) rArr (1)/(v) = (1)/(15) + (1)/(10) rArr (1)/(v) = (5)/(30)` `therefore v = +6` cm. The image is formed 6 cm BEHIND the mirror, it is a virtural and erect image. |
