Rotational MotionHard
Question
In the figure (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.More angular acceleration will be produced in (A)
B.More angular acceleration will be produced in (B)
C.Same angular accelration will be produced in both conditions
D.Information is incomplete
Solution
∴ Density of steel > Density of wood
∵ MI about O > MI about O
[in fig(a)] [in fig(b)]
∵ MI about O > MI about O
[in fig(a)] [in fig(b)]
