Question

The human body is composed mostly of water. Why does the Moon overhead cause appreciably less tidal effect in the fluid compartment of your body than a 1-kg melon held over your head does?

Answer 1

The force is inversely proportional to the square of radial distance and the mass of the lemon is compensated.

Step-by-step explanation:

• It is true that our body is composed mostly of water (precisely 75% of the body mass) which is influenced by the gravitational forces. This gravitational force in the water bodies cause tides.

We know that mathematically gravitational force is given as:

`F=G.(M_1.M_2)/(R^2)`

where:

R = radial distance between the masses

we observe that:

`F\propto(1)/(R^2)`

The force is inversely proportional to the square of radial distance.

• And the radial distance between the moon and a human on the earth is much greater than the distance between a lemon of low mass on the head of a human.
