Questions
Imagine a light planet revolving around a very massive star in a circular orbit of radius r with a period of revolution T. If the gravitational force of attraction between the planet and the star is proportional to , then T2 is proportional to
detailed solution
Correct option is C
Gravitational force =GMmR3/2 provides the necessarycentripetal force (i.e., mRω2 ) So GMmR3/2=mRω2=mR2πT2=4π2mRT2or T2=4π2R3/4GMe,i, T2∝R3/2Talk to our academic expert!
