(c) If you compare the gravitational force on the earth due to the sun to that due to the moon, you would find that the Sun’s pull is greater than the moon’s pull. However, the tidal effect of the moon’s pull is greater than the tidal effect of the sun. Why?

A star like the sun has several bodies moving around it at different distances. Consider that all of them are moving in circular orbits. Let r be the distance of the body from the centre of the star and let its linear velocity be v, angular velocity to, kinetic energy K, gravitational potential energy U, total energy E and angular momentum /. As the radius r of the orbit increases, determine which of the above quantities increase and which ones decrease.
