Statement A: Any physical or mental activity is termed as work done in...
Explanation:
The statement A is true. Let's understand the concept of work in physics.
Definition of Work:
In physics, work is defined as the product of force and displacement. When a force is applied on an object and the object moves in the direction of the force, then work is said to be done.
W = F x d
where W is the work done, F is the force applied, and d is the displacement of the object.
Understanding Statement B:
Statement B is partially true. When an object is displaced in the direction of applied force, work is said to be done. However, it is not necessary that work is always done in the direction of applied force.
For example, consider a person pushing a box on a rough surface. The force applied by the person is in the horizontal direction, but the displacement of the box is in the vertical direction due to the rough surface. In this case, work is still done even though the displacement is not in the direction of applied force.
Conclusion:
Hence, statement A is the correct statement. Any physical or mental activity is termed as work done in physics. It is important to understand the definition of work in physics, which involves the product of force and displacement. Work can be done even if the displacement is not in the direction of applied force.
