Question

Which one of the pictures below shows no work being done?

Select one:
a. The man trying to move the elephant.
b. The girl moving the wagon.
c. The same amount of work is being done.
d. Neither picture shows work being done.​

Answer 1

Answer:

A

Explanation:

No motion, no work.

The formula is W = F * d. If d is 0 then the work is 0.

I misread the original question. The elephant is not going anywhere soon. The girl is moving.

So the answer is A

Answer 2

Answer:

Option A

The man trying to move the elephant.

Explanation:

In the given picture we can see that

• “Man unable to move elephant”
• “A girl moving a wagon”

We know that

• Work done = Applied Force × Displacement

Here,

The girl is moving a wagon that means it displaces

So

W = F • d (distance be x)

W = Fx

Here, It shows work done

Now,

Man unable to move elephant that means it doesn't displaces, d = 0

So,

W = F • d (here d = 0)

W = F • 0

W = 0

Here, It shows no work done.
