Moment of inertia of a straight wire about an axis perpendicular to the wire and passing through one of its end is I. This wire is now framed into a circle (a ring) of single turn. The moment of inertia of this ring about an axis passing through centre and perpendicular to its plane would be :

1.	Moment of inertia of a straight wire about an axis perpendicular to the wire and passing through one of its end is I. This wire is now framed into a circle (a ring) of single turn. The moment of inertia of this ring about an axis passing through centre and perpendicular to its plane would be :
Answer» `((3)/(PI^(2)))I` `((3)/(4pi^(2)))I` `((pi^(2))/(3))I` `((4pi^(2))/(3))I` Answer :B
