## Homework Statement

A force ##F=4x## is applied on an object. What is work done to move it from ##x_1=2m## to ##x_2=4m##?

A)12 J

B)24 J

C)32 J

D)48 J

## Homework Equations

## The Attempt at a Solution

The displacement, ##x=4-2=2m##

Force, ##F=4x=4 \times 2=8N##

Work ##W=\vec F \cdot \vec x=8 \times 2 = 16 J##

But it is not listed in options. Did I miss anything? I guess it because Force was given as 4 times x, which will result in meters than Newtons.
