A) \[\frac{1}{2}m{{r}^{2}}\]
B) \[\frac{1}{4}m{{r}^{2}}\]
C) \[\frac{1}{2}m{{r}^{2}}+m{{x}^{2}}\]
D) \[\frac{1}{2}m{{r}^{2}}-m{{x}^{2}}\]
Correct Answer: D
Solution :
[d]: We know, \[{{I}_{C}}=m{{r}^{2}}/2\] Using parallel axes theorem, \[{{I}_{C}}={{I}_{CM}}+m{{x}^{2}}\] \[\therefore \]\[{{I}_{CM}}={{I}_{C}}-m{{x}^{2}}=m{{r}^{2}}/2-m{{x}^{2}}\]You need to login to perform this action.
