Question

1. A boy pushes a book by applying a force of 40N. Find the work done by this force as the book is
displaced through along
25 am along the path. ​

Answer 1

Answer:

$force \: = 40n$

$and \: displacement \: = 25m$

$work \: done \: = f \times s$

$work \: done = 40 \times 25$

$= 1000jule$

Answer 2

Given :-

Force applied by the boy = 40 N

Displacement along the path = 25 cm

To Find :-

The work done by the boy.

Analysis :-

Here we are given with the force and displacement.

Substitute the given values in the question using the formula such that work done is equal to the force multiplied by displacement.

Solution :-

We know that,

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

Using the formula,

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

Given that,

Force (f) = 40 N

Displacement (s) = 25 cm

Substituting their values,

⇒ w = 40 × 25

⇒ w = 1000 J

Therefore, the work done is 1000 J.
