दिया गया है कि
`m=6.0xx10^(24)kg, `
`M=2.0xx10^(30)kg,`
पृथ्वी तथा सूर्य के बीच कि औसत दुरी `r =15 ` करोड़ किलोमीटर
`=15xx10^(7)km=1.5xx10^(8)xx10^(3)=1.5xx10^(11)m`
तथा `G=6.7xx10^(-11)Nm^(2)//kg^(2).`
समीकरण `F=G(Mm)/(r^(2))`
`F=(6.7xx10^(-11)Nm^(2)//kg^(2))((2.0xx10^(30))xx(6.0xx10^(24)kg))/((1.5xx10^(11)m)^(2))`
`=35.7xx10^(21)N=3.6xx10^(22)N.`
अतः पृथ्वी तथा सूर्य के बीच गुरुत्वाकर्षण बल `3.6xx10^(22)N` है|
