Electricity and Magnetism Level 2

The above diagram shows a biconcave lens which has two focal points \(F_1\) and \(F_2\). The green object on the left of the lens is moving towards the lens at a constant speed of \(v\), and the beam A is travelling parallel to the lens axis. Which of the following statements is correct?

a) The beam A refracts towards the focal point \(F_2\).
b) The image of the object is placed on the left of the lens.
c) The location of the image gets closer to the lens as the object gets closer to the lens.
