6 Ns is the work done on the book to lift it by 3 m.
Answer:
Explanation:
Work done is the measure of amount of force required to move an object from its initial position to any desired position. So mathematically it can be calculated as the product of force acting on that object to the displacement of that object. Thus, work done on any object or by any object is directly proportional to the force acting on that object and the displacement of that object.
Work done = Force × displacement
As here the force is said to be 2 N and the displacement of the book is said to be 3 m, the work done on the book is
Work done = 2×3 = 6 N.s.
The time has no role to do on the work done calculation to be performed on the object.
Thus, 6 Ns is the work done on the book to lift it by 3 m.
