Parts and their functions

• Four side pairs (चार भुजा-युग्म) — Each at distance l: total −4Gm²/l.
• Two diagonal pairs (दो विकर्ण-युग्म) — Each at √2 l: total −2Gm²/(√2 l) = −√2 Gm²/l.
• Equal masses m (समान द्रव्यमान m) — Potential energy is summed over all 6 pairs.
• Centre O (केंद्र O) — Each mass is l/√2 away: potential V = −4Gm/(l/√2) = −4√2 Gm/l. The field here is zero by symmetry.
