Constant forces P(1)=hat(i)-hat(j)+hat(...

Constant forces `P_(1)=hat(i)-hat(j)+hat(k), P_(2)=-hat(i)+2hat(j)-hat(k)` and `P_(3)=hat(j)-hat(k)` act on a particle at a point A. Determine the work done when particle is displaced from position `A(4hat(i)-3hat(j)-2hat(k))` to `B(6hat(i)+hat(j)-3hat(k))` .
