Two satellites A and B move around earth in a circular orbit

In summary, a circular orbit is a path that a satellite takes around a central body, such as the Earth, while maintaining a constant distance from the center. Satellites stay in orbit due to a balance between their forward motion and the pull of Earth's gravity. Factors that affect a satellite's orbit include its mass, velocity, and distance from the central body, as well as other external forces. The orbits of satellites A and B can differ in terms of altitude, orbital period, inclination, and purpose. If their orbits intersect, there is a risk of collision, which is why careful planning and tracking of satellite orbits is necessary.

Two satellites A and B move around Earth in a circular orbit. The mass of B is twice the mass of A then
I agree that kinetic energy of B is greater than that of A. But what I couldn't understand was that why are speeds of A and B equal as given in the book.
Shouldn't they differ according to the formula: orbital velocity =(GM/R)^1/2

M is the mass of the Earth, not the satellite.

Thanks I got it.
 

What is a circular orbit?

A circular orbit is a path that a satellite takes around a central body, such as the Earth, in which the satellite maintains a constant distance from the center at all times.

How do satellites stay in orbit?

Satellites stay in orbit due to the balance between their forward motion, which keeps them from falling towards Earth, and the pull of Earth's gravity, which keeps them from flying off into space.

What factors affect a satellite's orbit?

The factors that affect a satellite's orbit include the mass and velocity of the satellite, the mass of the central body (such as Earth), and the distance between the satellite and the central body. Other factors such as atmospheric drag and gravitational pull from other bodies can also have an impact.

How do the orbits of satellites A and B differ?

The orbits of satellites A and B may differ in terms of their altitude, orbital period, or inclinations. They may also differ in terms of the purpose of their orbit, such as a communication satellite versus a weather satellite.

What happens if the orbits of satellites A and B intersect?

If the orbits of satellites A and B intersect, there is a risk of collision between the two satellites. To prevent this, satellite operators carefully plan and track the orbits of their satellites to ensure they do not cross paths.
