Question

1. A force of 7 N acts on an object.
The displacement is, say 8 m, in
the direction of the force
(Fig. 11.3). Let us take it that the
force acts on the object through
the displacement. What is the
work done in this case?

Please Solve ​

Answer 1

Answer:

56 Joules

Step-by-step explanation:

Given:

Force = 7 N

Displacement = 8 m

To find:

Work done = ?

Solution:

Work done (W) = Force applied (F) × Displacement traveled (s)

(putting values)...

=> W = 7 × 8

=> W = 56 J

Hence, we get the required ans

☆ SI unit of work done is Joules or Newton × meter (Nm)

Hope this helped you dear...

Answer 2

Given :-

The force acting on an object = 7 N

Displacement in  the direction of the force = 8 m

To Find :-

The  work done in this case.

Solution :-

We know that,

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

When a force acts on an object to displace it through a distance in its direction, then the work done on the body by the force.

By the formula,

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

Given that,

Force (f) = 7 N

Displacement (s) = 8 m

Substituting their values,

W = 7 × 8

W = 56 Nm = 56 J

Therefore, the work done is 56 J.
