Hi, I have a question and I hope anyone could answer it:
A uniform rectangular thin sheet ABCD of mas M has length a and breadth b as shown in the figure. If the shaded portion HBGO is cut-off, the coordinates of the centre of mass of the remaining portion will be –
(1)Â (5a/3 , 5b/3)
(2)Â Â (2a/3, 2b/3)
(3)Â (5a/12 , 5b/12)
(4)Â (3a/4, 3b/4)
(3)Â (5a/12 , 5b/12)
