The distance of the Sun from earth is 1.5 $\times$ 10¹¹ m and its angular diameter is (2000) s when observed from the earth. The diameter of the Sun will be :

A 2.45 $\times$ 1010 m
B 1.45 $\times$ 1010 m
C 1.45 $\times$ 109 m Correct answer
D 0.14 $\times$ 109 m

Solution

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