Block A of mass $1.0\ \text{kg}$ hangs from the ceiling by a light spring $S_1$. Block B of mass $2.0\ \text{kg}$ hangs from A by a light string, and block C of mass $1.0\ \text{kg}$ hangs from B by a light spring $S_2$, as shown in the figure. The system is at rest. The string between A and B is now cut. Take $g = 10\ \text{m/s}^2$. Which of the following statements are correct?

Fig. 1: Block A of 1.0 kg hangs from the ceiling by spring S1, block B of 2.0 kg hangs from A by a short string, and block C of 1.0 kg hangs from B by spring S2, all in one vertical line. The string between A and B is marked with a red cross and the word cut.
