The horizontal and vertical components of a force are 12.0 N and 5.0 N respectively, When this force acts on a particle, the particle is displaced 3.2 m along the horizontal axis and 1.5 m along the vertical axis. Express (a) force and (b) displacement in unit vectors.  Find (c) the work done by this force on the particle. (d) Find the angle between force and the displacement
