A uniform rod is hinged at its one end and is allowed to rotate in verticle plANE. Rod is given angular velocity `omega` in its verticle position as shown in figure. The value of `omega` for the force exerted by the hinge on rod is zero in this position is

`sqrt((g)/(L))`

`sqrt((2g)/(L))`

`sqrt((g)/(2L))`

`sqrt((3g)/(L))`
