If solving the question in 3D calculations is difficult, then use the 2D system to make the use of the theorem.

(a) True

(b) False

This question was addressed to me by my college professor while I was bunking the class.

The question is from Theorem of Pappus and Guldinus in section Centre of Gravity and Centroid of Engineering Mechanics

Best answer
Correct choice is (a) True

Explanation: The answer is obviously yes. If we are having any difficulty in making the vector components, then we can go in 2D. As if the particle is in equilibrium, the net force will be zero. No matter where you see first. Net force is zero.
