Given
mass of lighter Particle
mass of heavier Particle
speed of lighter particle
Let speed of heavier particle
and Momentum of the particle is given by





as momentum is conserved therefore 


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

here we know that


= 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
