In first figure a meter stick, half of which is wood and the other half steel is pivoted at the wooden end at A and a force is applied at the steel end at O. In second figure the stick is pivoted at the steel end at O and the same force is applied at the wooden end at A.The angular acceleration

a
in first is greater than in second
b
equal in both fust and second
c
in second is greater than in first
d
None of the above

detailed solution

Correct option is C

Torque will be same in both cases, but moment of inertia is less in second case, hence angular acceleration is greater in this case.
