Question

A force of 7 N acts on an object. The displacement is, say 8 m, in the direction

of the force. Let us take it that the force acts on the object through the

displacement. What is the work done in this case?​

Answer 1

Answer:

work=Force × displacement

=7N×8m

=56Nm

=56 J

Answer 2

GIVEN :

• Force = 7 N.
• The displacement = 8 m.

TO FIND :

• The work done = ?

FORMULA USED :

• W = F × S

Where,

W = work done.

F = force.

S = displacement.

SOLUTION :

To find the work done = ?

We know that,

Given force = 7 N and displacement = 8 m.

$\qquad \large \blue {\boxed {\tt W \ = \ F \times S}}$

Put the values in the above formula.

we get,

Work done = 7 × 8

Work done = 56 Joule.

$\qquad \large \red {\boxed {\tt Work \ done \ = \ 56 J}}$

•°• The work done in this case is 56 Joule.
