Two forces on a body in calm water:
-- Gravitational force, equal to the weight of the body (when it's in vacuum), directed down.
-- Buoyant force, equal to the weight of the water that would occupy the volume of the body if the body were not there, directed up.
If the body is actually "suspended" ... i.e. it will stay at any depth you place it, and will not rise or sink ...then it has "neutral buoyancy". The buoyant force is exactly equal and opposite to the gravitational force, so the NET force on the body is zero.

What occurs when forces acting upon a body are not balance?
When forces acting on a body are unbalanced, the body will experience acceleration in the direction of the net force. This acceleration causes the body to change its velocity, resulting in motion. The body will continue to accelerate until the forces acting upon it become balanced.
What is force acting on a body with uniform motion?
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
What are the forces acting on a roller coaster in a free body diagram?
In a free body diagram of a roller coaster, the forces acting on it are gravity, normal force, friction, and air resistance.
Is a body at equilibrium cannot be acted upon by external forces?
A body at equilibrium can still have external forces acting on it, but the net force acting on the body is zero. This means that the individual forces may cancel each other out, resulting in no acceleration or change in motion of the body.
When can a body stay at rest even though forces act on it?
A body can stay at rest even though forces act on it when the forces acting on the body are balanced, meaning they cancel each other out. This balance of forces results in no net force acting on the body, allowing it to remain at rest.

What occurs forces acting upon a body are not balanced?
The body accelerates.
What types forces does act on water tank?
The main forces acting on a water tank are the gravitational force pulling the water downwards, buoyant force acting upwards on the water due to the surrounding liquid or air, and the pressure forces exerted by the water on the walls and bottom of the tank. Depending on the situation, other forces like wind or external mechanical forces may also act on the tank.
What are the forces acting on a roller coaster in a free body diagram?
In a free body diagram of a roller coaster, the forces acting on it are gravity, normal force, friction, and air resistance.

What is net effect of two forces acting on a body?

When can a body stay at rest even though forces act on it?
A body can stay at rest even though forces act on it when the forces acting on the body are balanced, meaning they cancel each other out. This balance of forces results in no net force acting on the body, allowing it to remain at rest.
How many force act on a body floating in waterwhat are these forces?
A body floating in water has two forces acting on it: buoyant force pushing the body up and gravity pulling it down. The buoyant force is equal to the weight of the water displaced by the body, while gravity pulls the body downward.
What are the force acting on a body at rest?
When a body is at rest, the forces acting on it are balanced. These can include gravitational force pulling the body downward and normal force exerted by the surface supporting the body. As long as these forces are equal and opposite, the body remains at rest.
How can free body diagrams be used to analyze the forces acting on an object?
Free body diagrams can be used to analyze the forces acting on an object by visually representing all the forces acting on the object as vectors. By isolating the object and showing the direction and magnitude of each force, free body diagrams help in understanding how the forces interact and affect the object's motion or equilibrium.
What is equilibrant forces?
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
