Question

What would happen if the Sun's mass doubled in size?

A. The gravitational pull would DECREASE
B. The gravitational pull would INCREASE
C. The Sun's temperature would decrease
D. The Sun's brightness would decrease

Answer 1

If the Sun's mass doubled in size, the gravitational pull would increase.

Step-by-step explanation:

If the Sun's mass doubled in size, the gravitational pull would INCREASE.

According to the law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. When the mass of an object increases, the gravitational force it exerts also increases.

In this case, if the Sun's mass doubled, the gravitational force it exerts on other objects, including the planets in its solar system, would also double.
