Question

The distance of the Sun from earth is 1.5 $$	imes$$ 10
11
m and its angular diameter is (2000) s when observed from the earth. The diameter of the Sun will be :

Accepted Answer

Diameter = r $$	imes$$ $$\delta$$
$$ = 1.5 	imes {10^{11}} 	imes (2000) 	imes \left( {{1 \over {3600}}} ight) 	imes \left( {{\pi  \over {180}}} ight)$$
$$ = 1.45 	imes {10^9}$$ m
