A disc (of radius r cm) of uniform thickness and uniform density `sigma` has a square hole with sides of length `l = (r )/(sqrt(2)) cm`. One corner of the hole is located at the centre of the disc and centre of the hole lies y-axis as shown. Then the y-coordinate of position of centre of mass of disc with hole (in cm) is. .
