List of top Physics Questions on Satellite Motion and Angular Momentum

A planet \(P_1\) is moving around a star of mass \(2M\) in an orbit of radius \(R\). Another planet \(P_2\) is moving around another star of mass \(4M\) in an orbit of radius \(2R\). The ratio of time periods of revolution of \(P_2\) and \(P_1\) is:
A particle is moving in a circular path with constant angular velocity. Its initial angular momentum is L. If the radius of the circle is tripled by keeping angular velocity same, the new angular momentum is:

The time period of an earth’s satellite revolving at a height of 35,800 km is
If the string connecting \( m \) and the ground is cut, find the speed with which the \( 2m \) block hits the ground as shown. \( g = 10 \, \text{m/s}^2 \)
A satellite of mass \( \frac{M}{2} \) is revolving around Earth in a circular orbit at a height of \( \frac{R}{3} \) from the Earth's surface. The angular momentum of the satellite is \( M \sqrt{\frac{GM R}{x}} \). The value of \( x \) is:
