A uniform rod of length l λ and mass M is suspended on two vertical inextensible strings as shown in the figure. Calculate tension T in left string at the instant, when right string snaps.
A
B
mg
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Let the tension in the rope be T and the acceleration of the centre of mass of the rod downwards be a.
Then mg − − T = ma . . . (1)
Again, 
= I α α = 
´ ´ 
⇒ ⇒ a = 
. . . (2)
∴ ∴ T =
