A) \[43\,\,kg\,{{m}^{2}}\]
B) \[34\,\,kg\,{{m}^{2}}\]
C) \[27\,\,kg\,{{m}^{2}}\]
D) \[72\,\,kg\,{{m}^{2}}\]
Correct Answer: A
Solution :
[a] Moment of inertia of the whole system about the axis of rotation will be equal to the sum of the moments of inertia of all the particles. \[\therefore \] \[I={{I}_{1}}+{{I}_{2}}+{{I}_{3}}+{{I}_{4}}\] \[=0+0+27+16=43\,kg\,{{m}^{2}}\]You need to login to perform this action.
