A) \[2.5\times {{10}^{7}}\]
B) \[1.25\times {{10}^{7}}\]
C) \[2.5\times {{10}^{8}}\]
D) None of these
Correct Answer: C
Solution :
Moment of inertia of whole disc about an axis through centre of disc and perpendicular to its plane is \[{{200}^{0}}C\]. As one quarter of disc is removed, new mass \[{{300}^{0}}C\] \[0.18\times {{10}^{-3}}{{C}^{-1}}\]You need to login to perform this action.
