Question

Two satellites are revolving around the earth in circular orbits of same radii. Mass of one satellite is $100$ times that of the other. Then their periods of revolution are in the ratio:

• A. $100:1$
• B. $1:100$
• C. $1:1$
• D. $10:1$

Answer 1

The correct option is C $1:1$

Time period does not depend upon mass if satellite. It depends upon radius and mass of body around which they are rotating i.e earth radius so time period is in ratio $1:1$.
