- दबाव (P): प्रति इकाई क्षेत्र बल को दबाव कहा जाता है।
- दबाव की SI इकाई पास्कल (Pa) है।
दबाव (P) = बल (F) / क्षेत्र (A)
- बल (F) : किसी निकाय की विरामावस्था की अवस्था या गति की अवस्था को बदलने वाली अंतर्क्रिया को बल कहा जाता है।
- बल की SI इकाई न्यूटन (N) है।
बल (F) = द्रव्यमान (m) × त्वरण (a)
- घनत्व (ρ): प्रति इकाई आयतन द्रव्यमान घनत्व कहलाता है।
- घनत्व की SI इकाई प्रति घनमीटर किलोग्राम (kg/m3) है।
घनत्व (ρ) = द्रव्यमान (m) / आयतन (V)।
व्याख्या:
द्रव्यमान/आयतन = घनत्व।
तो विकल्प 3 सही है।
