# What is the Position of Image When an Object is Placed at a Distance of 10 Cm from a Convex Lens of Focal Length 10 Cm? - Science

What is the position of image when an object is placed at a distance of 10 cm from a convex lens of focal length 10 cm?

#### Solution

Given:
Object distance, u =   -10 cm
(Since object is always placed on the left side of lens)
Focal length, f = +10 cm
According to lens formula:

1/v-1/u=1/f

1/v=1/f+1/u

1/v=1/10=(-1/10)=0

v=1/0= oo

Therefore, the position of image will be at infinity.

Is there an error in this question or solution?
