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 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 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.


If a moving body has no acceleration does it mean no force acts on it?

There can well be forces acting on the body. It means that the NET FORCE (the vector sum of all the forces) acting on the object is zero.

How many forces are acting on a body which is at rest?

In most cases, when a body is at rest, there are two forces acting on it: the force of gravity pulling downward and the normal force pushing upward. These forces are equal and opposite, resulting in a balanced or net force of zero.
