Question

Let the preiod of revolution of aplanet at a distance R from a star be T. prove that if it was at a distance of 2R from the star , its period of revolution will be √8T.​

Answer 1

Answer:

Time period ( T ) is directly proportional to ( radius ) ^3/2

T final = ( R final / R intial )^3/2 ×T

=√8T
