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 and at `O`. On 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 (i) is greater than (ii)

B

in (ii) is greater than (i)

C

is equal in both (i) and (ii)

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
`tau=Fr=I_1 " " alpha_1=I_2 alpha_2`
As `I_1 > I_2`, hence `alpha_1 lt alpha_2` or `alpha_2 > alpha_1` .

In the figure (i) 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 (ii) the steel part is pivoted at O and the same force is applied at the wooden end

The adjacent figure shows a non-uniform metre stick AB having the linear mass density variation lambda = lambda_(0) x , where lambda_(0) is a constant and x is the distance from end A, placed on a smooth horizontal surface. In the first experiment, the rod is pivoted at A and force F is applied perpendicular to the rod at the other end B and in the second experiment, the rod is pivoted at B and the force is applied perpendicular to the rod at the end A. If in the first case angular acceleration is alpha_(A) and in the second case it is alpha_(B) then
