An object of size 5 cm is kept at a distance of 25 cm from the Optical centre of a converging lens of focal length 10 cm. Calculate the  size of the image. (along with sign).

A lens with a focal length of 35cm is used to form an image of an object. When this lens is placed a certain distance X from the object, no image is formed. Give this distance X in cm.
