For a variable force acting on an object fromPosition 1 to Position 2, the work done canbe approximated by W = EF, Ax. How canthe approximation be improved?

The formula for the work done by an object moving from position 1 to position 2 is given as
[tex]W=F_x\Delta x[/tex]The approximation of the work done can be improved by making the change in the position of the particle becomes smaller.
Hence, the correct answer is (a)
