Assertion – Reason type questions : For the following questions, statement as well as the reason(s) are given. Each questions has four options. Select the correct option. Statement – 1 : For a particle executing SHM, the amplitude and phase is decided by its initial position and initial velocity.

A block having mass M is placed on a horizontal frictionless surface. This mass is attached to one end of a spring having force constant k. The other end of the spring is attached to a rigid wall. This system consisting of spring and mass M is executing SHM with amplitude A and frequency f. When the block is passing through the mid-point of its path of motion, a body of mass mis placed on top of it, as a result of which its amplitude and frequency changes to A’ and f’. The ratio of frequencies $ { f' \over f } $ =..............................
