Question

N object weighing 20n in air weighs 10n in water. Find the volume of the object. (density of water = 997 kg/m

Answer 1

Given Data:
997— density of water

1 m3 = 1 unit volume

10 m/s2— acceleration of gravity.

Equation for liquid:

W=mg…20 = m

mass= 10 = (1000kg/m3)*V*10 m/s2

Submerged Volume in liquid:

V=

Equation for air:

W=mg…10 =m* 10

mass=1.02 kg

10 =(997kg/m3)*V*9.81 m/s2

Submerged Volume in air:

V=

Answer 2

volume of water =997kg/M3

mass exerted. 10n

let volume be v

997=10n/v

v=10n/997

v=0.01n
