An aligned optical system consists of two thin lenses with focal lengths fl and 12, the distance between the lenses being equal to d. The given system has to be replaced by one thin lens which, at any position of an object, would provide the same transverse magnification as the system. What must the focal length of this lens be equal to and in what position must it be placed with respect to the two-lens system?

Answer:
An object on which no net force is acting is not necessarily at rest; the object could be moving with a constant velocity. Newton's first law states that An object at rest or in motion will remain unless the object experiences a net external force . ... Newton's Second Law of Motion relates force, mass, and acceleration.
