Average distance of the earth from the sun is L_(1). If one year of the earth=D days, one year of another planet whose average distance from the sun is L_(2) will be

Answer»

`D((L_(2))/(L_(1)))^(1//2)`DAYS
`D((L_(2))/(L_(1)))^(3//2)`days
`D((L_(2))/(L_(1)))^(2//3)`days
`D((L_(2))/(L_(1)))`days

Solution :According to Kepler.s third law,
`T^(2) prop R^(3). or " T prop r^(3//2)`
`:. (D.)/(D)=((L_(2))/(L_(1)))^(3//2)" or D.=D((L_(2))/(L_(1))^(3//2))" days"`
