Assuming all pulleys, springs and string massless. Consider all surface smooth. Choose the correct statement(s).

Answer:

Solution:

String constraint: if the block moves by $x$ , $x = \frac{y _{1} + 2 y _{2} + 2 y _{3}}{2}$ .

Force equations: $Δ T = ma$ , $2Δ T = K y_{2}$ , $2Δ T = K y_{3}$ , $\frac{Δ T}{2} = K y_{1}$ .

Solving, $x = Δ T (\frac{33}{4 K})$ , so $ma = \frac{4 K}{33} x$ .

$ω^{2} = \frac{4 K}{33 m} \Rightarrow ω = \frac{4 K}{33 m}$ - (B)
