If solving the question in 3D calculations is difficult, then use the 2D system and then equate the total work done to zero.

(a) True

(b) False

I got this question in an interview for job.

My question is taken from Work in section Principle of Virtual Work of Engineering Mechanics

Best answer
Right option is (a) True

For explanation I would say: The answer is obviously yes. If we are having any difficulty in making the vector components, then we can go to 2D. As if the particle is in equilibrium, the net force will be zero. No matter where you see first. Network done is zero.
