Answer:
1. 3) only a constant gravitation force that acts downward
2. b) Equal to the accleration at the surface of the asteroidc)
Explanation:
1.
- In absence of atmosphere, the force that will act on the steroid is the force of gravity due to asteroid.
- Gravitational force is a long range force acting always attractive in nature.
- It is a contact-less field force which does not requires a medium.
Mathematically given as:
where:
G = gravitational constant
are the mass of the two objects
radial distance between the two objects.
2.
The acceleration of the ball at the top height of the path is still under the influence of the gravity of the two masses so it will be equal to the acceleration due to gravity at the surface of the asteroid. Acceleration always remains constant.
