Question

vi. A uniform rod of mass 2m is held horizontal
by two sturdy, practically inextensible
vertical strings tied at its ends. A boy of
mass 3m hangs himself at one third length
of the rod. Ratio of the tension in the string
close to the boy to that in the other string is
(A) 2
(B) 1.5
(C) 4/3
(D) 5/3​

Answer 1

Answer:

I think (c) 4/3 is correct answer

I hope it's help you plz make me brainlist

Answer 2

Answer:

(B) 1.5

Explanation:

Lets take tension in string is T₁ and T₂

By balancing force in vertical direction

  T₁  + T₂ = 2 m g + 3 m g

  T₁  + T₂ = 5 m g

By taking moment about left end

Take clockwise positive

3 m g .L/3 + 2 m g .L/2 = T₂ L

m g L + m g L = T₂ L

T₂= 2 m g

  T₁  + T₂ = 5 m g

  T₁  + 2 m g = 5 m g

  T₁   = 3 m g

So

T₁ / T₂ = 3 /2 = 1.5

T₁ / T₂ =1.5

(B) 1.5
