In the figure a uniform disc of radius \( \mathrm{R} \), from which
P a hole of radius \( \mathrm{R} / 2 \) has been cut out from left of the

W centre and is placed on right of the centre of disc. Find the centre of mass of the resulting disc.
(1) \( \frac{\mathrm{R}}{3}, 0 \)
(2) \( \frac{\mathrm{R}}{2}, 0 \)
(3) \( \frac{\mathrm{R}}{4}, 0 \)
(4) \( \mathrm{R}, 0 \)
