Question

A body is subjected to a constant force given by F(N) = -i+2j+3k. What is the work done by this force in moving the body through a distance of 4m along the z-axis and then 3m along the y-axis?

Answer 1

Answer:

we know that work done = force× displacement so,

when it moves along z-axis then work =3×4= 12 N/m.

and when it moves along y-axis

work =2×3=6 N/m
