Mechanical Properties Of Fluid

The work obtained in bringing a body from infinity to a point in a gravitational field is called the gravitational potential energy of the body at that point.

where is gravitational constant, is mass of earth its radius and is mass of body.
Also for a body projected upwards at a certain velocity of projection the body will go out of the gravitational field of the earth and will never return to the earth, this initial velocity is called escape velocity.

Since, work is required to take a body from earth's surface to infinity, we have

Dividing E (3) by (2), we get

Volume of big drop Volume of droplets ie,


For smaller drop,

For bigger drop,
