वजन:
- हे गुरुत्वाकर्षण बल आहे जे वस्तूला पृथ्वीच्या केंद्राकडे आकर्षित करते.
- याचे एकक न्यूटन (N) आहे.
जिथे, W = वस्तूचे वजन, m = वस्तूचे वस्तुमान, g = गुरुत्वीय त्वरण.
घनता:
- एका वस्तूच्या वस्तुमानाचे तिच्या घनाशी असलेले गुणोत्तर अशी त्याची व्याख्या केली जाते.
- याचे एकक kg/m3 आहे.
जिथे,
गणना:
दिलेल्याप्रमाणे:
धातूची घनता, ρ = 5000 kg/m3
वजन, W = 10.8 N
g = 10 m/s2
आता, वजन (W) = mg
जिथे, m धातूचे वस्तुमान आहे
तर,
घन (v) = 0.000216 मिटर3 = 216 सेमी3
म्हणून, पर्याय (1) योग्य उत्तर आहे.
