సరైన సమాధానం 10 N.

కీలక 

  • చంద్రుని ఉపరితలంపై వస్తువు బరువు 10 N ఉంటుంది.
  • ఇవ్వబడినది
    • భూమి ఉపరితలంపై వస్తువు బరువు (We) = 60 N
    • చంద్రునిపై వస్తువు బరువు
    • భూమి యొక్క ఉపరితలంపై కొలిచినప్పుడు ఒక వస్తువు 60 N బరువు ఉంటుంది.
    • చంద్రుని ఉపరితలంపై దాని బరువు 10 N ఉంటుంది.

అదనపు సమాచారం

  • భూమి యొక్క గురుత్వాకర్షణ చంద్రుని గురుత్వాకర్షణ కంటే చాలా ఎక్కువ కాబట్టి భూమి మరియు చంద్రునిపై ఉన్న వస్తువు యొక్క బరువు భిన్నంగా ఉంటుంది.
  • న్యూటన్ నియమం ప్రకారం F=mg, ఇక్కడ F బరువు మరియు M ద్రవ్యరాశి, మరియు G అనేది గురుత్వాకర్షణ వలన త్వరణం అయితే చంద్రునిపై గురుత్వాకర్షణ భూమి కంటే చాలా తక్కువగా ఉంటుంది.
  • ఒక వస్తువు బరువు భిన్నంగా ఉంటుంది.
  • ద్రవ్యరాశి మరియు గురుత్వాకర్షణ క్షేత్ర బలాన్ని అనుసంధానించే సూత్రం:
    • గురుత్వాకర్షణ శక్తి = ద్రవ్యరాశి × గురుత్వాకర్షణ క్షేత్ర బలం (g)
  • ఇందులో:
    • గురుత్వాకర్షణ శక్తిని న్యూటన్ (N)లలో కొలుస్తారు
    • ద్రవ్యరాశిని కిలోగ్రాముల (kg)లలో కొలుస్తారు
    • గురుత్వాకర్షణ క్షేత్ర బలం (g) కిలోగ్రాముకు న్యూటన్‌ (N/kg)లలో కొలుస్తారు
