Question

Machine A moves a weight of 10 N of cotton by 5 m. Machine B

moves a weight of 0. 5 N of iron by 100 m. Which machine does

more work? Justify your answer.​

Answer 1

Answer:

both machine does the same work

Explanation:

as work done =force/ displacement

Answer 2

Given:-

• Force exerted by Machine (A), F = 10N

• Displacement ,s = 5

• Force exerted by Machine (B) ,F' = 0.5N

• Displacement ,s' = 100m

To Find:-

• Which machine work more .

Solution:-

As we know that Work Done is defined as the product of Force and displacement.

• W = Fs

For Machine 'A'

Work done by machine 'A'

→ W = Fs

Substitute the value we get

→ W = 10×5

→ W = 50 J --------------(i)

Therefore, the work done by the machine A is 50 Joules.

______________________________________

Work done by Machine 'B'

→ W' = F's'

Substitute the value we get

→ W' = 0.5 × 100

→ W' = 50 J ---------------(ii)

Therefore, the work done by the machine 'B' is 50 Joules.

_____________________________________

From the equation (i) & (ii) we observe that

The machine A & Machine B work same .
