An object is plac

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


Lens Formula



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.
