Question

a man carrying a bucket of water and walking on a level road with uniform velocity does on work while carrying the bucket which of the following statements give the correct reason for this the displacement of the bucket is in the direction of force apply there is no displacement in the direction of the force applied when is no force acting on the bucket the displacement of the particle is zero​

Answer 1

Explanation:

Yes, when a man is carrying a bucket on a level road with uniform velocity work is not done.

This is because work is not done when the force applied is perpendicular to the direction of displacement. when it is so it becomes 0 work done or no work.

Answer 2

1. It is true that a man carrying a bucket of water and walking on a level road with uniform velocity does no work while carrying the bucket.

2. The statement that gives the correct reason for this is-

There is no displacement in the direction of the force applied.

3. Mathematically, work is the product of force and the displacement in the direction of force.

4. This is termed as dot product of force and displacement.

5. The force (weight of man and bucket) and displacement, are perpendicular to each other.

6. Hence the work done is zero.
