Question

Two artificial satellites of unequal masses are revolving in a circular orbit around the earth with a constant speed. Their time periods.

• A. will be different.
• B. will be same.
• C. will depend on their masses.
• D. will depend upon the place of their projection.

Answer 1

The correct option is B will be same.

The time period of the satellite depends upon the speed and radius of satellite but not on the mass. So, if two satellites have same speed and are in same orbit the time periods are same i.e. $t=\frac{2\pi r}{v}$ is same for either of the satellites.
