(i)
From Eqs. (i) and (ii), 
From Eq. (ii), 
Note: But if only normal reaction applied by the rod is considered to be 2 N
II Law 
(i)
(ii)
Next Question :
A uniform rod 
of mass 2 kg is hinged at one end 
.The rod is kept in the horizontal position by a massless string tied to point
. Find the reaction of the hinge (in N) on end 
of the rod at the instant when string is cut
