Four point masses each of mass , are proved at the corners of a square of side . The square is rotating with angular frequency , about an axis passing through one of the corner of the square and parallel to its diagonal , as shown in figure. The angular momentum of the square about this axis is :-
Option: 1
Option: 2
Option: 3
Option: 4
Since, BD is parallel to axis.
Half of the diagonal square
Also,
= Equal to the diagonal of square =
Because all the masses are same = m
By putting the value of r1, r2 , r3
We get
So, Angular momentum =
Angular momentum =
