Answer :

__Given__

The distance of object from the lens = - 60 cms (since the object is on the left-hand side of lens and acc. To our sign convention)

The focal length of the convex lens = +30 cms ( focal length of convex length is positive.)

Height of object = 3 cm

__Formula Used__

Magnification formula

Using lens formula

V = + 60 cms

Hence the image is at a distance of 60 cms from the lens and the image is real.

Using magnification formula

M =

M = -1

Hence, the image is of the same size as that of object and the image is __inverted.__
