Question

A pair of bullocks experts a force of 250N on a plough. The field being ploughed is 3.5m long. How much work is done in ploughing the length of the field ?​

Answer 1

Answer:

875 J

Step-by-step explanation:

Work = FScos0

As Force and Displacement are in the same direction, So the angle between them is 0

Value of cos0 = 1

Work = FS × 1

W = 250 × 3.5 × 1

W = 875 J

Answer 2

Given :-

Force applied = 250 N

Displacement = 3.5 m

To Find :-

Work done in ploughing the length of the field.

Analysis :-

Here. we are given with the force and displacement.

Substitute the given values in the formula of work and get it accordingly.

Solution :-

We know that,

• w = Work
• s = Displacement
• f = Force

Using the formula,

$\underline{\boxed{\sf Work \ done=Force \times Displacement}}$

Given that,

Force (f) = 250 N

Displacement (s) = 3.5 m

Substituting their values,

w = 250 × 3.5

w = 875 J

Therefore, 875 J work is done in ploughing the length of the field.
