In order to get the cork to inst float in the water, a number ofstones are carefully placed on top of the cork block such that none ofthe stones is immersed in the water. Each stone is of mass 75 3. Determine the number, N, of stones required. Include an appropriate sketch in your solution. [5] Density of water = 103 ngIl-J
