Question

A coolie was standing with 2 suitcases on his head and 2 bags in his hand. The luggage exerted a force of 159 N on him. What is the amount of work done by him?&#8203;a)79.5 Jb)318 Jc)0 Jd)159 JCorrect answer is option 'C'. Can you explain this answer?

Answer

We know that coolie is not moving in specific direction (no displacement).So,work done is zero there is no displacement of the coolie.

Answer

0j

Answer

Displacement = 0
W = 0 J

Answer

O Joule , because the angle between work done and force is equal to 90 degree.

Answer

2 condition need to be satisfied for work to be done
First-force should be applied
second-their should be some displacement.
Here the second condition is not satisfied. Hence work done is oJ

Answer

The amount of work done by the coolie can be determined using the formula:

Work = Force × Distance

In this case, the force exerted by the luggage on the coolie is 159 N. However, in order to calculate the work done, we need to know the distance over which the force is applied.

Since the question does not provide any information about the distance, we cannot calculate the work done by the coolie. Therefore, the correct answer is option 'C', which states that the work done is 0 J.

It's important to note that work is only done when there is a displacement in the direction of the force applied. In this case, without the knowledge of the distance, it is not possible to determine if there was any displacement and therefore, any work done.

To summarize:
- The formula to calculate work is Work = Force × Distance.
- The force exerted by the luggage on the coolie is 159 N.
- However, without knowing the distance over which the force is applied, the work done cannot be calculated.
- Therefore, the correct answer is option 'C' which states that the work done is 0 J.

Answer

Because there is no any displacement takes place...So displacement =0
And if Force is multiplied by displacement i.e., F×S= F × 0= 0 Joules .............

Answer

When coolie was  standing with 2suitcases in his  head and 2 bagsin his hand then he does not move any where so in this case according to physics when body displace then work is done but coolie is standing in one place so work is 0

Answer

0 j
