That depends how fast the object moves. However, once it falls in the water at a constant velocity, you know that the net force - which is just what the question is after - is zero.

Why have to put minus sign before the formula of gravitational potential?
The minus sign is required because the gravitational potential is attractive. The sign denotes exergy, giving energy out !
A object of mass 80kg slides down a vertical pole with an acceleration of 4 meters per second What is the friction force that acts on the object?
Assuming the object is within the Earth's gravitational field and assuming the gravitational field of the Earth during the object's acceleration is constant at 9.81 N Kg-1. The force that the object should be experiencing is a product of the object's mass an velocity thus the force it should be experiencing is 80 multiplied by 9.81. However, the object has a acceleration of 4. Thus, the resultant force it has now is 80 multiplied by 4. Using algebra, 80*9.81 minus 80*4 ca be simplified to 80(9.81-4) which equals 80 multiplied by 5.81. The magnitude of the fictional force is 80 multiplied by 5.81 which is 464.8 Newtons.
How do you find an objects acceleration from its mass and the force acting on it?
Acceleration= total force / mass. Total force might be applied force minus frictional force, or applied force minus air resistance etc.
How do you canculate net force?
Net force is the resultant force, so it is the applied force minus all the opposing forces
What is gravitational equilibrium?
Mass times acceleration minus dynamic pressure squared times area times coefficient of drag
What is the mathematical proof of gravitation force between antimatter to antimatter and matter to antimatter?
Sir Issac Newton proposed the law of gravitational force between mass to mass of matter. That is the gravitational force between to masses is directly proportional to the product of masses and inversely proportional to the square of distance between the two. F=G* m1*m2/r2. Here the F is the force of gravity. G is gravitational constant. m1 is mass one. m2 is mass 2. r is the distance between the masses. Now for the two masses of antimatter you have to denote the negative sign to the mass. So the formula is F = G* minus m1 * minus m2 / r2. So here the F is positive number. So there will be force of attraction between the two masses of antimatter. Hence proved.Now you take one mass of matter and another mass of antimatter. The formula is F = G * m1* minus m2 / r2. Here the F is negative number. So there is no force of attraction between the two. Instead there is force of repulsion. So the force of repulsion between the mass of matter and mass of antimatter is directly proportional to the product of masses of matter and antimatter and inversely proportional to the square of distance between the two. Hence proved.So above is the mathematical proof of the gravitational force between the masses of antimatter and antimatter and gravitational force between the masses of antimatter and matter.

How is the sun and it's planets are attracted?
The sun and its planets are attracted to each other through gravitational forces. Gravity is the force of attraction between any two objects with mass. The sun's immense mass creates a gravitational pull that keeps the planets in their orbits, causing them to revolve around the sun.

What is Planet Jupiter's gravitational pull factor?
The general law of gravity gives the gravity force between two objects in terms of their masses and their distance apart. The force between two objects is: F = G M1 M2 / R-squared If G = 6.670E-11 and the masses M1 and M2 are in kilogrammes, and the distance R is in metres, then the force comes out in Newtons. In the above equation 6.670E-11 means 6.670 times ten to the power of minus eleven. This web site has a fault in the font which means it is impossible to use the normal notation.

Acceleration= total force / mass. Total force might be applied force minus frictional force, or applied force minus air resistance etc.
How many plus and minus are there in frictional force?
Only one minus: the frictional force acts in the direction opposite to that of motion.
What forces are acting on a book that is lying on a table?
Gravitational force (weight), pointing down.Reaction force, equal to the gravitational force (weight), exerted by the tabletop, pointing up.
An even number minus a odd number?
"IT IS ALWAYS A ODD"
What is a minus number divided by a minus number?
A plus number.
An odd number minus an odd number?
An odd number minus an odd number is an even number.
What is the force between a boy sitting on a chair?
The force is exactly equal to the weight of the boy, provided his feet are not resting on the floor. If they are, the force between the boy and the chair is the boy's weight minus the force between his feet and the floor. Remember, in physics weight is a force due to gravity and not a property of matter (mass). The weight of the boy can be calculated from his mass (given that he is subject to the known gravity of earth) at roughly 10 Newtons per Kg.
