Question

Which scenario represents the weakest force? (Assume particles in all scenarios are the same distance apart.)

Protons and neutrons are held together inside the nucleus.
Two particles are attracted to one another by static electricity.
An unstable atom breaks down releasing two radioactive particles.
Two rocks of equal mass fall to the ground at the same speed.

Answer 1

Two rocks of equal mass fall to the ground at the same speed is the scenario represents the weakest force.

Answer: Option D

Step-by-step explanation:

There are four fundamental forces existing in the Universe and the weakest force is gravitational force amongst them. This force is also responsible for the particle to fell down on the earth because of its weakest attraction force as compared to the other forces applied on the object.

It is the force between two object masses and here given is at equal distance. So, when two rocks with equal speed and mass at a same distance should be the case of showing weakest force.

Answer 2

Two rocks of equal mass fall to the ground at the same speed.

Step-by-step explanation:

The four basic forces also called the fundamental forces as they are responsible for all observations of forces in nature.

The four fundamental forces are gravity, electromagnetism, weak nuclear force, and strong nuclear force.

The gravity is the weakest one.
