a body of weight 10 n is kept on a smooth horizontal table.what is the force exerted on the table by the body

To find the force exerted on the table by the body, we need to use Newton's second law, which states that force is equal to mass multiplied by acceleration (F = m * a). In this case, we know the weight of the body, which is a force acting vertically downward due to gravity, but we need to find the force exerted horizontally on the table.
Since the body is on a smooth horizontal table, there is no acceleration in the horizontal direction. Therefore, the force exerted horizontally on the table is zero.
In other words, when an object is at rest or moving with constant velocity on a smooth horizontal surface, the force exerted by the object horizontally is balanced by an equal and opposite force exerted by the surface. This force is called the normal force.
In this case, the normal force exerted by the table on the body is equal in magnitude but opposite in direction to the weight of the body (10 N downwards). Therefore, the force exerted on the table by the body is 10 N upwards, equal in magnitude but opposite in direction to the weight of the body.
Gravity acts on bodies of mass m with a force of mg equal to its weight.
g is the acceleration due to gravity.
The given weight is 10N, so gravity is already included, and the net force acting on the table is 10N.
