Question

if the mass of an object is 3 kg and is volume is hundred centimeter Cube the object will float or sink into the water​

Answer 1

GIVEN :-

$\textsf{The mass of an object(m) = 3 kg = 3000 g}$

$\sf{Volume\ of\ the\ object(V) = 100 cm\³}$

TO FIND :-

Whether the object will sink or float.

FORMULA TO BE USED :-

$\displaystyle{\sf{Density=\frac{Mass}{Volume} \:\:\:\:\:(p=\frac{m}{V} )}}$  

SOLUTION :-

$\displaystyle{\sf{Density\ of\ the\ object=\frac{3000}{100} }}$

$\boxed{\displaystyle{\sf{\implies p=30\ gcm^{-3} }}}$

$\sf{We\ know\ that\ the\ density\ of\ water=1\ g/cm\³}$

$\sf{So,\ we\ conclude\ that,}\\\\\boxed{\sf{Density\ of\ object>Density\ of\ water}}$

$\therefore\bold{\underline{\text{Thus, the object will sink in water.}}}$

Answer 2

Answer:

Sink

Explanation:

Given:

Mass of the object = 3 kg = 3000g

volume = 100 cm³

To find:

Whether the object will sink or float

So we know that:

Density = $\frac{Mass}{Volume}$

By substituting the above values, we get:

Density = $\frac{3000}{100}$

Density = 30 g/cm³

If the density of a object is more than 1 g/cm³, then it will sink and if it is less than 1g/cm³, then it will float. (30g/cm³>1g/cm³)

Here the density is more than that of water, so it will definitely sink.

The object will sink in this case
