A circular disc of radius r = 5m rotating in a horizontal plane about y-axis. y-axis is vertical axis passing through the centre of disc and xz is the horizontal plane at ground. The height of disc above ground is h = 5m. Small particles are ejecting from disc in horizontal direction with (in m) speed 12 m/s from the circumference of disc then calculate the distance of these particles from origin where they hits the x-z plane. 1)11 2)12 3)13 4)14
