Vedclass · Answer

(C) According to Kepler's second law,the areal velocity of a planet is constant,which is given by $\frac{dA}{dt} = \frac{L}{2m}$.Here,$L$ is the angular momentum and $m$ is the mass of the planet.Since the gravitational force exerted by the Sun on the planet is a central force,the torque acting on the planet about the Sun is zero $(	au = 0)$.Because $	au = \frac{dL}{dt}$,if $	au = 0$,then $L$ must be constant.Therefore,the motion of satellites or planets in the solar system is an example of the conservation of angular momentum.

In planetary motion,the areal velocity of the position vector of a planet depends on the angular velocity $(\omega)$ and the distance of the planet from the sun $(r)$. If so,the correct relation for areal velocity is:

The time period of a satellite of the Earth is $5 \text{ hours}$. If the separation between the Earth and the satellite is increased to four times the previous value, the new time period of the satellite will be: (in $\text{ hours}$)
