Calculate the work done when a force F = 2 i + 3 j – 5 k units acts on a body, producing a displacement S = 2 i + 4 j + 3 k units

Q: Calculate the work done when a force $\vec{F} = 2 \hat{i} + 3 \hat{j} – 5 \hat{k} $ units acts on a body, producing a displacement $ \vec{S} = 2 \hat{i} + 4 \hat{j} + 3 \hat{k} $ units

(a) 30 units

(b) 45 units

(c) 1 unit

(d) zero

Ans: (c)
