    Figure shows a rod of length L resting on a wall and the floor. Its lower end A is pulled towards left with a constant velocity 2v. Which of the following is the velocity of the other end B downward when the rod makes an angle (() with the horizontal?                                

    A)  \[R/4\]             

    B)  \[R/2\]

    C)  \[R/8\]        

    D)  \[\left\{ \frac{{{(1+e)}^{2}}}{1+{{e}^{2}}} \right\}\sqrt{\frac{gh}{2}}\]

    Correct Answer: D

    Solution :

                    In such type of problems, when velocity of one part of a body is given and that of other is required, we have to relate them first, we can write,     \[\alpha \] and                        \[2\omega [1-2\alpha \Delta T]\] Again                     \[\omega [1-\alpha \Delta T]\] or,                          \[\omega [1+2\alpha \Delta T]\] or                            \[\omega [1+2\alpha \Delta T]\] \[P+Q+R+S\]                      \[\overline{P}\overline{Q}\overline{R}\overline{S}\]
