In a cylindrical vessel of diameter 24 cm filled up with sufficient quantity of water, a solid spherical ball of radius 6 cm is completely immersed. Then the increase in height of water level is :
-
- 1.5 cm
- 2 cm
- 3 cm
- 4.2 cm
- 1.5 cm
Correct Option: B
If the height of increased water level be h cm, then
| ⇒ | = 3 | |
| 3 |
| ⇒ 12 × 12 × h = | × 6 × 6 × 6 | |
| 3 |
| ⇒ h = | 2cm | |
| 12 × 12 |
