Question

In figure (a), a meter stick half of which made of wood and the other half of steel is pivoted at the wooden end at O and a force is applied to the steel end at a. In figure (b) the stick is pivoted at the steel end at O and the same force is applied at the wooden end at $\mathrm{a}^{1}$. The angular acceleration\
