Answer:
Explanation:
As per Kepler's III law we know that time period of revolution of satellite or planet is given by the formula
now for the time period of moon around the earth we can say

= mass of earth
Now if the same formula is used for revolution of Earth around the sun
here we know that
= mass of Sun
now we have
