Answer: 11 Joule
Explanation: Work done (W) is dot product of Force (F) and displacement (S) vectors.
Displacement vector, S = (1 hat i + 2hat j + 1 hat k) m
Force vector, F = (3hati + 2hatj + 4hatk) N
Work done (W) = vec F . vec S
= (3hati + 2hatj + 4hatk) . (1 hat i + 2hat j + 1 hat k)
= (3 + 4 + 4)
= 11 Joule
