Spring force in spring 2 before cutting $=2\mathrm{mg}$ Spring force in spring 1 before cutting $=\mathrm{mg}$ just after cutting the string spring forces do not change. For $\mathrm{A}:{\mathrm{k}}_2\mathrm{x}-2\mathrm{mg}=2{\mathrm{ma}}_{\mathrm{A}}\Rightarrow {\mathrm{a}}_{\mathrm{A}}=0$

For $\mathrm{B}:{\mathrm{k}}_2\mathrm{x}+2\mathrm{mg}=4\mathrm{mg}=2{\mathrm{ma}}_{\mathrm{B}}\Rightarrow {\mathrm{a}}_{\mathrm{B}}=2\mathrm{g}$

For $\mathrm{C}:{\mathrm{k}}_1\mathrm{x}+\mathrm{mg}=2\mathrm{mg}={\mathrm{ma}}_{\mathrm{C}}\Rightarrow {\mathrm{a}}_{\mathrm{C}}=2\mathrm{g}$
