संकल्पना:

  • दाब (P): प्रति एकक क्षेत्रफळाच्या बलाला दाब म्हणतात.
    • दाबाचे एसआय एकक पास्कल (Pa) आहे. 

दाब (P) = बल (F)/ क्षेत्रफळ (A)

  • बल (F): पदार्थाची विश्रांतीची स्थिती किंवा गतीची स्थिती बदलणाऱ्या परस्परक्रियेला बल म्हणतात.
    • बलाचे एसआय एकक न्यूटन (N) आहे.

बल (F) = वस्तुमान (m) × त्वरण (a)

  • घनता (ρ): घनफळाच्या प्रति एकक वस्तुमानाला घनता म्हणतात.
    • घनतेचे एसआय एकक किलोग्राम प्रति घनमीटर (किलो/मी3आहे.

घनता (ρ) = वस्तुमान (m)/घनफळ (V).

स्पष्टीकरण 

वस्तुमान/घनफळ = घनता.

म्हणून, पर्याय 3 योग्य आहे.
