A measuring jar of internal diameter 10 cm is partially filled with water. Four equal spherical balls of diameter 2 cm each are dropped in it and they sink down in water completely. What will be the change in the level of water in the jar?
Volume of a sphere = (4/3)πr3
Volume of a cylinder = πr2h
Amount of water displaced = Volume of the spheres
Given, measuring jar of internal diameter 10 cm is partially filled with water. Four equal spherical balls of diameter 2 cm each are dropped in it and they sink down in water completely.
Let the rise in level of water be ‘h’ cm.
⇒ h = 16/75 cm
