A force F = x 2 y 2 i + x 2 y 2 j (N) acts on a particle which moves in the XY plane.
(a) Determine F is conservative or not and
(b) Find the work done by F as it moves the particle from A to C (fig.) along each of the paths ABC, ADC, and AC.
Dear student,
(a)If F is conservative then
(b)The work done by the given force is
Along AB, y=0 so WAB =0,
Along BC,dx =0 so
Thus work done is
Along AD,x=0, WAD =0
Along DC,dy=0
Along AC,x=y,dx=dy
​Regards.
