किसी स्थान पर गुरुत्वीय क्षेत्र उपस्थित है एवं किसी द्रव्यमान को \(A\) से \(B\) पर अलग-अलग पथों द्वारा चित्र में दर्शाये अनुसार विस्थापित किया जाता है। यदि \(W_1, W_2\) एवं \(W_3\), गुत्वीय बल द्वारा अलग-अलग क्रमशः पथों के अनुदिश किए गए कार्य हैं, तो :

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
