Statement I The weight of a person in a satellite is the same as that on the earth’s surface.
Statement II The weight of an object is equal to gravitational force between the object and the planet.

Answer 1

Explanation for statement I:

1. A person in a satellite feels weightless because the radius and mass of the satellite is such that the gravitation forces due to satellite negligible.
2. On the Earth's surface there is a force acting on a person. Hence person has weight on the surface of weight.

Explanation for statement II:

1. The gravitation force between the earth and object is called weight.
2. It is equal to the product of acceleration due to gravity and mass of the object.

Hence, statement I is False, statement II is True. Option (d) is correct
