A uniform rod of mass m and length l is ...


A uniform rod of mass `m` and length `l` is applied pivoted at point `O`. The rod is initially in vertical position and touching a block of mass `M` which is at rest on a horizontal surface. The rod is given a slight jerk and it starts rotating about point `O` this causes the block to move forward as shown The rod loses contact with the block at `theta=30^(@)` all surfaces are smooth now answer the following questions.
Q. The velocity of block when the rod loses contact with the block is

A

`(sqrt(3gl))/(4)`

B

`(sqrt(5gl))/(4)`

C

`(sqrt(6gl))/(4)`
