Question

an object of 10 centimetre height is placed at a distance of 36 cm from a concave mirror of focal length 12 cm find the position nature and height of its image​

Answer 1

Explanation:

Object distance u=−36 cm

Focal length of concave mirror f=−12 cm

Using mirror formula : +

1/v + 1/-36 = 1/-12

⟹ v=−18 cm

Magnification

10 h i = −10−(−18)

⟹ h i =−18 cm

Image formed is real and inverted.
