The magnification of an object plac ed in front of a convex lens of focal length 20 cm is +2. to obtain a magnification of -2. the object will have to be moved a distance equal to

The magnification of an object placed it front of a convex lens of focal length 20cm is +2 . To obtain a magnification of -2 , the object will has to be moved a distance equal to

A convex lens of focal length 15 cm produces a magnification of +4 . The object is placed:

The linear magnification of an object placed on the principal axis of a convex lens offocal length 30cm is found to be +2. In order to obtain a magnification of -2, by how much distance should the object be moved?

Distance of an object from a concave lens of focal length 20 cm is 40 cm. Then linear magnification of the image

Distance of an object from a concave lens of focal length 20 cm is 40 cm. Then linear magnification of the image

Where should an object placed from a conveging lens of focal length 20 cm,so as to obtain a real image of magnification 2?

Where should an object be placed from a converging lens of focal length 20 cm, so as to obtain a real image of magnification 2?

Where should an object be placed from a converging lens of focal length 20 cm, so as to obtain a real image of magnification 2?

The magnification of an object placed in front of a convex lens is +2 . The focal length of the lens is 2.0 metres. Find the distance by which object has to be moved to obtain a magnification of -2 (in metres).
