Question

1. how does the mass of an object influence its gravitational field? *

a. larger mass means a weaker field
b. mass has no effect on gravity
c. larger mass means a stronger field
d. smaller mass creates a gravitational field

1. what would happen to a spaceship that gets very close to a black hole? *

a. it would orbit safely
b. it would become invisible
c. it would increase speed
d. it would be pulled toward the black hole

Explanation:

• For question 5: According to Newton's law of universal gravitation \(F = G\frac{m_1m_2}{r^2}\), the gravitational force (and by extension, the gravitational field which is related to the force per unit mass) is directly proportional to the mass of an object. A larger mass means a stronger gravitational influence (field). Option A is wrong as larger mass does not mean weaker field. Option B is incorrect because mass is a key factor in gravity. Option D is wrong as both large and small masses create gravitational fields, and the question is about the influence of mass on the field's strength.
• For question 6: Black holes have extremely strong gravitational forces. A spaceship close to a black hole would be pulled in due to the black hole's gravitational pull. Option A is incorrect as being very close (not in a stable orbit distance) won't result in safe - orbiting. Option B is wrong as becoming invisible is not a direct consequence of being close (unless crossing the event horizon, but the more immediate effect is the pull). Option C is incorrect as the main effect is the pull towards the black hole, not just speed increase (the speed increase is a result of the gravitational pull, but the primary outcome is being pulled in).

Answer:

1. C. Larger mass means a stronger field
2. D. It would be pulled toward the black hole
