Explanation
Mass of satellite does not affect its orbital radius.
Because distance of point C is maximum from the sun.
Earth revolves around the sun in circular path and required centripetal force is provided by gravitational force between earth and sun but the work done by this centripetal force is zero.
If the orbital path of a satellite is circular, then its speed is constant and if the orbital path of a satellite is elliptical, then its speed in its orbit is not constant. In that case its area! velocity is constant.
Angular momentum
In a spaceship orbiting around the earth, g = 0.
Therefore a pendulum clock cannot be used for measuring time.
The period of a satellite in a circular orbit is independent of mass of the satellite.
The effective gravity inside the satellite is zero, so weight of a person inside the satellite is zero.
According to Kepler’s third law T2 ∝ r3 ; At r = 0, T = 0. It shows that the graph between T2 and r3 is a st. line passing through origin.
