. A marble sphere with a diameter of 1/4 inch is fully immersed in the oil of density 0.961 g/cm3 . Calculate the buoyant force exerted on the marble sphere by the oil.

Respuesta :

Answer:

See below    ( was it REALLY 1/4 INCH??)

Explanation:

Calculate the volume of the sphere

v = 4/3 pi r^3

 this times the density of the oil will give g displacement

   then f = ma

4/3 pi (.25 in  * 2.54 cm/inch) ^3  * .961 = 1.0307 gm

1.0307 gm   is   .0010307 kg

f = ma = .0010307 * 9.8 = .0101 N
