Answer 1

The turning effect of a force acting on a body about an axis is due to the moment of force or torque. It depends on the magnitude of a force applied and the distance of the line of action of force from the axis of rotation. Moment of a Force (Torque):

buoyant force is the upward force a fluid exerts on an object. Archimedes' Principle is the fact that buoyant force is equal to the weight of the displaced fluid.

Answer 2

Answer:

1)Now according to the definition of moment, when a force acts on any object in the perpendicular direction of that object then it creates a turning effect in the object and the object turns or rotates on its own axis. Thus, it can be said that the turning effect of the force is called Moment.

2)So when an object is immersed in a fluid, then the bottom part of the object will have more pressure than the top part of the object. Due to this pressure difference, the object feels a force that is acting in an upward direction. This force on the object is called the buoyant force
