Question

The ratio of distance of the sun from the earth to that of the moon from the earth is in the order:

• A. \( 10^6 \)
• B. \( 10^3 \)
• C. \( 10^4 \)
• D. \( 10^5 \)

Hint:

The average distance from the Earth to the Sun is about 400 times larger than the average distance from the Earth to the Moon.

Answer 1

The Correct Option is A

The average distance from the Earth to the Sun is approximately \( 1.496 \times 10^8 \) km. The average distance from the Earth to the Moon is approximately \( 3.844 \times 10^5 \) km.
Thus, the ratio of the distance from the Earth to the Sun and the Earth to the Moon is: \[ \frac{\text{Distance from Earth to Sun}}{\text{Distance from Earth to Moon}} = \frac{1.496 \times 10^8}{3.844 \times 10^5} \approx 3.89 \times 10^2 \]
Thus, the ratio is approximately \( 10^3 \), so the correct answer is \( 10^6 \).
