“An object is placed at a distance of 10cm from convex mirror of focal length15cm; find the position and nature of image?”

Ans:

f= 15 cm

u=-10 cm

v=?

substitute the values in the relation

$\frac{1}{f}=\frac{1}{v}+\frac{1}{u}$

and get the value of v as 6 cm

The image is virtual, erect and diminished
