Best answer
पृथ्वी की त्रिज्या R = 6400 किमी ` = 6.4 xx 10 ^(6) ` मीटर
` therefore ` आधारक b = पृथ्वी का व्यास = ` 2xx 6.4 xx 10 ^(6) `
` = 1.28 xx 10 ^(7) ` मीटर
लम्बन कोण ` theta = 1 ` मिनट = ` (( 1 ) /( 60 ) ) ^(@) `
` = ( 1) /(60) xx ( pi ) /(180 ) ` रेडियन
यदि पृथ्वी से पिण्ड की दुरी D हो, तो
` theta = (b) /(D) `
` therefore D = (b) /( theta ) = (1.28 xx 10 ^(7))/( (1) /( 60 ) xx ( pi) /(180)) `
` = ( 1.28 xx 60 xx 180 xx 10 ^(7)) /( 3.14 ) = 4.4 xx 10 ^(10) ` मीटर
` = ( 4.4 xx 10 ^( 10 ) ) /( 1.5 xx 10 ^( 11)) ` खगोलीय मात्रक
` = 0.293 ` खगोलीय मात्रक
