What is the formula for finding gravitational force inside water ?
gravitational force inside the water
Answer:
The gravitational force acting on an object is the same in air, or in water. However, in water the effect of gravity is partially counteracted by the object's buoyancy, which is equal to the weight of the water it is displacing.
For example, a cube of concrete with a volume of 1 cubic foot weighs 150 lbs. If you put this cube of concrete under water, gravity is still pulling down on the cube with a force of 150 lbs, but the water is pushing up on the cube with a force of 62.4 lbs. (1 cubic foot x 62.4 lbs/cubic foot) Therefore, the net force acting on the cube is 87.6 lbs.
If you weigh the cube under water, the scale will say it weighs 87.6 lbs, but the gravitational force is still 150 lbs.
you need to be more specific... are you referring to a mass submerged in water? the force due to gravity on any object remains the same whether it's in water, air, peanut butter, etc.
if the object is in water there may be additional forces acting on it such as the pressure due to the water. if the object is relatively large you may have the situation where you have greater pressure on the bottom (pushing up) than on top (pushing down), as such the total force pushing down should be less.
remember the pressure increases with depth.
hope this helps, although really need more information to give a specific answer.
