 Three blocks A, B and C are suspended as shown in the figure. Mass of each blocks A and C is m. If system is in equilibrium and mass of B is M, then :
                
  • a)
     M = 2m (
  • b)
     M<2m
  • c)
     M > 2m
  • d)
     M = m
Correct answer is option 'B'. Can you explain this answer?

Three blocks A, B and C are suspended as shown in the figure. Mass of ...

Given,
Mass of block A & B = m
Mass of block C = M
Let,
Mass of A = mA​ & Mass of B = mB
Tension in string is = T
At equilibrium, T = mA​g = mB​g = mg
Weight of block C is = Mg 
Forces on block C,
2Tcosθ = Mgcosθ
⇒ Mg/2T = Mg/2mg
⇒ ​M/2m
If 0< θ <90° then 1> cosθ >0
1> M/2m >0
2m > M
Hence, 2m > M
