A uniform rod of mass kg and length  is suspend by two smooth hinges 1 and 2 as shown in Fig. A force N is applied downward at a distance  from hinge 2. Due to the application of force  hinge 2 breaks. At this instant, applied force  is also removed. The rod starts to ratate downward about hinge 1. )

The reaction at hinge 1, before hinge 2 breaks, is

a)

24N

b)

12N

c)

11N

d)

10N
