Image of an object at infinity is formed by a convex lens of focal length $30cm$ such that the size of the image is $2cm$. If a concave lens of focal length $20cm$ is placed in between the convex lens and the image, at a distance $26cm$ from the convex lens, size of the new image is:

Q. The size of the image of an object, which is at infinity, as formed by a convex lens of focal length $30cm$ is $2cm$. If a concave lens of focal length $20cm$ is placed between the convex lens and the image at a distance of $26cm$ from the convex lens, calculate the new size of the images.

Q. A convex lens of focal length $30cm$ forms an image of height $2cm$ for an object situated at infinity. If a concave lens of focal length $20cm$ is placed coaxially at a distance of $26cm$ in front of convex lens the size image would be

Q. The size of the image of an object, which is at $\infty ,$ is formed by a convex lens of focal length $30\text{cm}$ is $2\text{cm}.$ If a concave lens of focal length $20\text{cm}$ is placed between the convex lens and the image at a distance of $26\text{cm}$ from the convex lens. Find the new size of the image-

Q. A thin convex lens of focal length $30.00cm$ forms an image $2.00cm$ high, of an object at infinity. A thin concave lens of focal length $20.00cm$ is placed $26.00cm$ from the convex lens on the side of the image. The height of the image now is
