Question

Necessary condition for the application of parallel axes theorem:
$I_A=I_B+M{d}^2$
where $A\text{and}B$ are the axes of rotation of body and $M$ is the mass of body.

• A. Axis $B$ must pass through C.O.M of body
• B. Axis $A$ must be parallel to axis $B$
• C. $d$ must be shortest distance between axis $A$ and axis $B$
• D. All of these

Answer 1

The correct option is D All of these

Necessary condition for the application of perpendicular axes theorem:
$I_A=I_B+M{d}^2$
where $A\text{and}B$ are the axes of rotation of body and $M$ is the mass of body are
1. Axis $B$ must pass through C.O.M of body
2. Axis $A$ must be parallel to axis $B$
3. $d$ must be shortest distance between axis $A$ and axis $B$
