1. Which law of motion is related to the concept of gravitation?
a) Newton’s first law
b) Newton’s second law
c) Newton’s third law
d) None of the above

Answer: d) None of the above. The concept of gravitation is described by Newton’s law of universal gravitation, not his laws of motion.

2. Which of the following quantities affects the gravitational force between two objects?
a) Mass of one object
b) Mass of both objects
c) Distance between the objects
d) Both mass and distance

Answer: d) Both mass and distance. The gravitational force is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between them.

3. The value of acceleration due to gravity:
a) Varies with altitude
b) Varies with latitude
c) Varies with both altitude and latitude
d) Remains constant everywhere on Earth

Answer: c) Varies with both altitude and latitude. The acceleration due to gravity decreases with increasing altitude and slightly varies with different latitudes due to the Earth’s shape.

4. The escape velocity from Earth:
a) Depends on the mass of the object
b) Depends on the height from which it is launched
c) Is the same for all objects regardless of their mass
d) None of the above

Answer: c) Is the same for all objects regardless of their mass. The escape velocity from Earth is constant and does not depend on the mass or height of the object.

5. If the distance between two objects is doubled, the gravitational force between them will:
a) Double
b) Halve
c) Quadruple
d) Remain the same

Answer: b) Halve. The gravitational force is inversely proportional to the square of the distance between two objects. Doubling the distance reduces the force to one-fourth (or halves it).

6. Which of the following is responsible for the gravitational force?
a) Neutrons
b) Electrons
c) Protons
d) Mass

Answer: d) Mass

7. The force of gravity between two objects is dependent on:
a) Mass of both objects
b) Distance between the objects
c) Both mass and distance
d) Neither mass nor distance

Answer: c) Both mass and distance

8. The value of acceleration due to gravity:
a) Varies from place to place on Earth
b) Is constant throughout the universe
c) Decreases with increasing altitude
d) All of the above

Answer: a) Varies from place to place on Earth

9. The value of acceleration due to gravity on the Moon is approximately _______ that on Earth.
a) One-tenth
b) One-fourth
c) Half
d) The same as

Answer: d) The same as

10. If the mass of an object is doubled and the distance between two objects is also doubled, the gravitational force between them will be:
a) Doubled
b) Halved
c) Quadrupled
d) Unchanged

Answer: d) Unchanged

11. The gravitational force between two objects is inversely proportional to the:
a) Mass of one object only
b) Mass of both objects
c) Square of the distance between the objects
d) Cube of the distance between the objects

Answer: c) Square of the distance between the objects

12. The gravitational force acting on an object is maximum at:
a) The surface of the object
b) Halfway between the surface and the center of the object
c) The center of the object
d) There is no maximum, it remains constant throughout

Answer: c) The center of the object

13. The escape velocity of an object depends on:
a) The mass of the object only
b) The radius of the object only
c) Both the mass and radius of the object
d) Neither the mass nor the radius of the object

Answer: c) Both the mass and radius of the object

These are just a few sample questions to get you started. Remember to thoroughly study the topic of gravitation and solve additional practice questions to further enhance your understanding.
