Question

An object is placed perpendicular to principal axis of a convex mirror of focal length 10cm the distance of the object from the pole of the mirror is 10cm find the position of image formed

Answer 1

Answer:

The image is formed 5cm behind the mirror.

Explanation:

f = 10 cm (+ve)

u = 10 cm (-ve)

=> 1/f = (1/v)+(1/u)

=> 1/10 = 1/v+ 1/-10

=>1/v = (1/+10) - (1/-10)

=>1/v = (1/10)+(1/10)

=>1/v = 2/10

=> v = 10/2

=> v = 5 cm (+ve)
