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 = ?
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.
