Question

How would the absence of gravity affect the formation of planets?
(A)The rocks and debris would take longer to accrete into a planet.
(B)The rocks and debris would never accrete into a planet.
(C)The rocks and debris would accrete into a smaller orbiting body.
(D)The rocks and debris would be pushed closer to the Sun.

Answer 1

In the absence of gravity, the rocks and debris
would never accrete into a planet. (B)

Also by the way, it wouldn't matter much, because
there wouldn't be a star to orbit around, AND orbits
wouldn't exist either.

Answer 2

Answer:

(B)The rocks and debris would never accrete into a planet.

Explanation:

During the formation of planets, rocks and debris aggregate together because of the gravity. Gravity, in fact, is the force exerted between every object that has mass. The magnitude of the force of gravity is given by

$F=G\frac{m_1 m_2}{r^2}$

where

G is the gravitational constant

m1 and m2 are the masses of the two particles

r is the distance between the two particles

Without the force of gravity, there will be no force that would accrete the rocks and the debris into a planet.
