A particle is acted upon by the forces ...

A particle is acted upon by the forces ` vec F_(1)= hati + 2hat j+ 3 hat k , vecF_(2)= 2 hat i + hat j - 3 hatk , vecF_(3) = 3 hat i - 4 hatj + 2 hat k,` is displaced from the point ` (-2, 1, 3)` to the point `(1, lambda, -2 )`. If the total work done by the forces is 8. Find the value of ` lambda` .
