1.	Two satellites going in the equatorial plane have almost same radii. As seen from the earth one move from east to west and the other from west to east. Will they have the same time period as seen from the earth? If not, which one will have less time period?
Answer» As seen from the earth, the apparent time period for both the satellite will be different due to the rotation of the earth. The earth rotates from west o east. So, the satellite moving from east to west will have greater relative angular speed, hence, will have less time period.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
