In the above problem,If the size of the image formed at the positions are`6cm and 3cm` then the height of the object is

In the above problem height=____cm.

A convex lens forms a real image of an object for its two different positions on a screen. If height of the image in both the cases be 8 cm and 2 cm , then height of the object is

A convex lens forms a real image of an object for its two different positions on a screen. If height of the image in both the cases be 8 cm and 2 cm , then height of the object is

In displacement method, convex lens forms a real image of an object for its two different positions. If heights of the images in two cases be 24 cm and 6 cm, then the height of the object is

In displacement method, convex lens forms a real image of an object for its two different positions. If heights of the images in two cases be 24 cm and 6 cm, then the height of the object is

An object is kept at a distance of 16 cm from a thin lens and the image formed is real. If the object is kept at a distance of 6 cm from the lens, the image formed is virtual. If the sizes of the images formed are equal, the focal length of the lens will be

An object is kept at a distance of 16 cm from a thin lens and the image formed is real. If the object is kept at a distance of 6 cm from the lens, the image formed is virtual. If the sizes of the images formed are equal, the focal length of the lens will be

An object is kept at a distance of 16 cm from a thin lens and the image formed is real. If the object is kept at a distance of 6 cm from the lens, the image formed is virtual. If the sizes of the images formed are equal, the focal length of the lens will be

An object is kept at 20 cm in front of a convex lens and its real image is formed at 60 cm from the lens . Find the height of the image if the height of the object is 6 cm.
