Question

A 24 cm radius aluminum ball is immersed in water. Calculate the thrust you suffer and the force. Knowing that the density of aluminum is 2698.4 kg / m3

Answer 1

W =1562.53 N

Step-by-step explanation:

It is given that,

Radius of the aluminium ball, r = 24 cm = 0.24 m

The density of Aluminium,
`d=2698.4\ kg/m^3`

We need to find the thrust and the force. The mass of the liquid displaced is given by :

`m=dV`

V is volume

Weight of the displaced liquid

W = mg

`W=dVg`

So,

`W=dg* (4)/(3)\pi r^3\\\\W=2698.4* 10* (4)/(3)* \pi * (0.24)^3\\\\W=1562.53\ N`

So, the thrust and the force is 1562.53 N.
