JEE MAIN - Physics (2022 - 27th June Evening Shift - No. 2)
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 :
2.45 $$\times$$ 1010 m
1.45 $$\times$$ 1010 m
1.45 $$\times$$ 109 m
0.14 $$\times$$ 109 m
Explanation
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
