A real object is place a distance d from a converging lens.The object is then moved to a distance 2d from the converging lens.Which of the following statements is false?
A)The image in the first case with the object at distance d can be the larger one.
B)The image in the second case with the object at distance 2d can be the larger one.
C)If both images are real,the image in the second case is smaller.
D)If the image in the first case is real,the image in the second case is upright.

Option D is false because if the image in the first case is real, it must be inverted according to the laws of refraction, and when the object is moved to a distance 2d from the lens, the image will also be inverted. So, the image in the second case will not be upright. Options A, B, and C are all true statements. The image in the first case can be larger or smaller, depending on the position of the object with respect to the lens. Similarly, the image in the second case can also be larger or smaller. If both images are real, the image in the second case will be smaller as the distance between the object and the lens is increased.
