Froces acting on a particle have magnitude 5,3,1 and act in the direction of the vectors (6,2,3),(3m-2,6),(2,-3,-6) respectively. These remain constant while the particle is displaced form the point `A(4,-2,-6) to B(7,-2,-2)`. Find the work done by the forces.

Forces acting on a particle have magnitude of 14N, 7N and 7N act in the direction of vectors 6hat(i)+2hat(j)+3hat(k),3hat(i)-2hat(j) +6hat(k),2hat(i)-3hat(j)-6hat(k) respectively. The forces remain constant while the particle is displaced from point A: (2,-1,-3) to B: (5,-1,1). Find the work done. The coordinates are specified in meters.

If forces of magnitudes 6 and 7 unit acting in the directions i-2j+2k and 2i-3j-6k respectively act on a particle which is displaced from the point P(2,-1,-3) to Q(5,-1,1), then the work done by the forces is

Forces of magnitudes 5 and 3 units acting in the directions 6hati + 2hatj + 3hatk and 3 hati - hati +6hatk respectively act on a particle which is displaced from the point ( 2,2,-1) to ( 4,3,1) . The work done by the forces, is

Two forces whose magnitudes are 2N and 3N act on a particle in the direction of the vectros 2hati+4hatj+4hatk and 4hati-4hatj+2hatk respectively. If the particle is displaced from the origin O to the point (1,2,2). Find the work done.

If the constant forces 2hati-5hatj+6hatk and -hati+2hatj-hatk act on a particle due to which it is displaced from a point A (4,-3,-2) to a point B (6,1,-3), then the work done by the forces is
