PhysicsSingle correct+4 / -1Question 32 of 90

The distance of the Sun from earth is $1.5\times10^{11}$ m and its angular diameter is (2000) s when observed from the earth. The diameter of the Sun will be :

2.45\times10^{10}

1.45\times10^{10}

1.45\times10^9

0.14\times10^9

Answer and worked solution

Official answer: C

Angle. $2000''=\dfrac{2000}{3600}°\approx9.70\times10^{-3}$ rad.

Diameter. $1.5\times10^{11}\times9.70\times10^{-3}\approx1.45\times10^9$ m.

(C)
