A planar object made up of a uniform square plate and four semicircular discs of the same thickness and material
\( \mathrm{P} \) is being acted upon by four forces of equal magnitude as

W shown in figure. The coordinates of point of application of forces is given by
(1) \( (0, a) \)
(2) \( (0,-a) \)
(3) \( (a, 0) \)
(4) \( (-a, 0) \)
