Question

An object of mass 10 kg and volume 0.5 m is submerged. Is it float or sink in water? Density of water is 1000kg ​

Answer 1

Answer:

Let the volume of the boat is V and the volume of water displaced be the boat is

2

V

So, Mass of water displaced be the boat is,

=

2

V

×densityofboat

=

2

V

×

V

M

=

2

M

=

2

10

=5Kg(M=10Kg given)

So, the mass displaced by boat is 5Kg

The force required to wholly submerge it into water is,

=mg

=5×9.8

=49N
