The distance of the Sun from earth is 1 . 5 × 10 11 m and its angular diameter is 2000 '' when observed from the earth. The diameter of the Sun will be

Options

  1. A2 . 45 × 10 10   m
  2. B1 . 45 × 10 10   m
  3. C1 . 45 × 10 9   m
  4. D0 . 14 × 10 9   m

Correct answer

C. 1 . 45 × 10 9   m

Step-by-step solution

Diameter of Sun is D = r θ = 1.5 × 10 11 × ( 2000 ) × 1 3600 × π 180 = 1.45 × 10 9   m
