Answer
(a) R is the most probable position of its centre of gravity.
(b) When a body is freely suspended from a point, it comes to rest (i.e. stops oscillating) in such a position that its centre of gravity lies vertically below the point of suspension. So, in the figure, the string from the branch passes vertically through point R, hence R is the most probable position of the kite’s centre of gravity.
