A) \[{{m}^{3}}\]
B) \[{{m}^{3}}\]
C) \[{{m}^{3}}\]
D) \[{{m}^{3}}\]
Correct Answer: C
Solution :
Key Idea: Use parallel axes theorem. From the theorem of parallel axes, the moment of inertia (I) of a body about given axis is equal to its moment of inertia I about its diameter, plus the product of the mass m of the body and square of perpendicular distance between the two axes. That is \[{{v}_{p}}=2{{v}_{e}}=2\times 11.2\] \[=22.4km/s\]You need to login to perform this action.
