An object is plac

Given

The distance of object from lens = -10cm (since the object is on the left-hand side of lens and acc. To our sign convention)

Focal length of convex lens = + 40cm (focal length of convex length is positive)

The distance of image from Lens = ?

Formula Used

Lens Formula

Magnification formula

Using lens formula

V = = -13.33cm

Hence, the image is on the same side of object at the distance of 13.33 cm from lens and the image is virtual.

Using magnification formula

M = 1.33

The image is 1.33 times the object and is erect.
