Question

Calculate the work done in displacing an object from(1,2,3) to (6,8,9) by applying a force of f=6i+2j+3k

Answer 1

Answer:

Step-by-step explanation:

As we know work done = force x distance

Magnitude of force is sqrt(6*2+2*2+3*2)=7N

Similarly distance =7root 2

So the product is 49 root 2J
