The force exerted on an object is F.
Find the work done in moving the object from x =
O to x = 3a.​

Answer 1

Answer:

3fa

Explanation:

because w=f×displacement ,

so ans is 3fa.

Answer 2

Answer:

$3aF$

Explanation:

We are given that force exerted on an object =F

We have to find the work done in moving the object form x=0 to x=3a

We know that work done=Force multiplied by  displacement

Displacement :It is the distance between two points.

Displacement =final position-initial position

Displacement =3a-0=3a

Work done=$F\times (3a)=3aF$

Hence, work done in moving the object from 0 to 3a =3a F
