Two circular discs of radius each $\displaystyle 10$ cm are joined at their centres by a rod of length $\displaystyle 30$ cm and mass $\displaystyle 600$ gm as shown in figure.If the mass of each disc is $\displaystyle 600$ gm and applied torque between two discs is $\displaystyle 43 \times 10^5$ dyne.cm, the angular acceleration of the discs about the given axis $\displaystyle A B$ is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{rad} / \mathrm{s}^2$.
