In the fig. (a) half of the meter scale is made of wood while the other half of steel. The wooden part is pivoted at O.A force F is applied at the end of steel part. In figure (b) the steel part is pivoted at O' and the same force is applied at the wooden end:

Options

A. The angular acceleration will be greater for the stick in figure. 1. because the torque about Q is greater than the torque about O'
B. The angular acceleration will be greater for the stick in figure 2, because the torque about O' is greater than the torque about O.
C. The angular acceleration will be greater for the stick in figure 1 because the rotational inertia about O is smaller than the rotational inertia about O'
D. The angular acceleration will be greater for the stick in figure 2 because the rotaional ineria about O' is smaller man the rotational ineria about O.

Answer

`B, D`
