Distance of two planets from the sun are...

 Distance of two planets from the sun are 10^11 m and `10^(10)` m respectively. Then find the ratio of time period of these two planets.

Text Solution

Verified by Experts

`implies T_1/T_2 =((R_1)/R_2)^(3/2)=(10^(11)/(10^(10)))^(3//2) = 10^(3/2) = 10sqrt10`
