Which of the following forces was involved in the formation of the Sun?
Answer options:
A.
Electrostatic force
B.
Gravitational force
C.
Magnetic force
How to approach this question
Consider the forces that act over large distances and involve large masses. Which force is responsible for pulling together the dust and gas that formed the Sun?
Full Answer
B.Gravitational force✓ Correct
Gravitational force
The formation of the Sun began with a large cloud of dust and gas (a nebula). The gravitational force, which is an attractive force between all objects with mass, caused this cloud to collapse in on itself. As it collapsed, the material became denser and hotter, eventually leading to the formation of the Sun.
Common mistakes
✗ Confusing gravity with other fundamental forces like electrostatic or magnetic forces.
