18. Two identical sleeves A and B each of mass m can slide without friction on a fixed horizontal rod. A load C of mass 2m is suspended from the mid-point of a light inextensible cord of length I = 3/5 m connecting the sleeves A and B. Initially the sleeves are at a separation I and the load is held motionless. What can you conclude for subsequent motion after the load is released? Acceleration of free fall is 10 m/sº. (a) Maximum speed of the sleeves is v10 m/s. (b) Maximum speed acquired by the load C is 2v5 m/s. (c) The load descends a height 1.5 m to acquire maximum speed. (d) Before the sleeves collide, the net force on the system consisting of the sleeves, the cord and the load becomes zero once.

Applications Of Reflection Of Light

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
