Question

PLz.............. answer this question
The weight of a metallic spheres,each of 200 g and radius 4 cm and 10 cm respectively are measured in water and vacuum.how will the ratio of their weights change in water and in vacuum.Explain

Answer 1

Answer:

17:50

Explanation:

volume of sphere = (4/3) πr3 = 2.68*10^-4 m3

Bouyancy force is acted upon by every fliud in upward direction on every body.

Bouyancy force = weight of volume of fluid displaced by the body . = 2.68*10^-4 * 1000 = 0.268 Kg = 268 gm
