When a force of (5i + 2j + 3k) is applied on an object, then it displaces by a displacement

Question

When a force of \((5\hat{i} + 2\hat{j} + 3\hat{k})\) is applied on an object, then it displaces by a displacement of (\((10\hat{i} + 12\hat{j} + 14\hat{k})\) m. Calculate the work done by the force on the object.

Answer 1

= 50 + 0 + 0 + 0 + 24 + 0 + 0 + 0 + 42

= 116 J
