Find the work done by the force vecF=2hati+hatj+hatk acting on a particle, if the particle is displaced from the point with position vector 2hati+2hatj+2hatk to the point with position vector 3hati+4hatj+5hatk .

Find the work done by the force vecF=hati+2hatj+hatk acting on a particle, if the particle is displaced from the point with position vector 2hati+hatj+hatk to the point with position vector 3hati+2hatj+4hatk .

Three constant forces vecF_1=2hati-3hatj+2hatk , vecF_2=hati+hatj-hatk , and vecF_3=3hati+hatj-2hatk in newtons displace a particle from (1, -1, 2) to (-1, -1, 3) and then to (2, 2, 0) (displacement being measured in meters). Find the total work done by the forces.
