Forces of magnitude `5sqrt(2)and10sqrt(2)` units acting in the directions `3hat(i)+4hat(j)+5kand10hat(j)+6hat(j)-8hat(k),` respectively, act on a particle which is displaced from the point with position vector `4hat(i)-3hat(j)-2hat(k)` to the with position vector `6hat(i)+hat(j)-3hat(k).` Find the work done by the forces.
