Constant force P = 2i - 5j + 6k and Q = -1 + 2j - k act on a particle. When the particle is displaced from A (4, - 3, -2) to B (6,1, - 3) then the work done is

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
