How far from a very small 100 kg ball would a particle have to be placed so that the ball pulled on the particle just as hard as the earth does?

2.61*10^-5
You get this from (GMm)/r^2=9.8
G=6.67*10^-11
Cancel out M because it is very small and is negligible.
m=100kg
solve for r

What is small particle?
A small piece of matter. Depending on the context, it may be a grain of dust, or something much smaller, such as a molecule, an atom, or a subatomic particle.
What is a heating event?
it is a small particle that contains burnable elements.
What is a nonviable particle?
Nonviable means that something is not alive nor can it be made to be alive. You sometimes hear that a fetus is too young to be alive if it is born. They are called nonviable fetuses. A particle usually means a piece of something small or a part of something small.
What properties of light define it as a wave?
An experiment was conducted in relation to this theory. A extremely small object (dot0 was placed in the path of light. If light is considered to be traveling in straight lines, then a small shadow should have been formed. However, in this case no shadow is formed. Meaning that light has bypassed the object... Such bypass is only possible when light is wavy in nature... How light is both wavy and particle in nature.
Why water vapour is not pulled due to gravity?
A water vapour is a tiny particle of water its weight(mg) is very very small almost negligible so it is not pulled by gravity.
If action is equal to reaction why isn't the earth pulled into orbit around the communication satellite?
The earth is pulled by the satellite, but because the gravitational force of the satellite is so small and the Earth is so big the effect is negligable.
Which subatomic particle is very small?
Proton is a positive particle and electron is a negative particle.
What is a small particle?
Iota
What is the smallest subatomic particle Hobbs?
If you think to the boson Higgs this is not a small particle.
a small negatively charge particle that orbits the nucleus?
This elementary particle is the electron.
How did the moon get sucked into the earths gravity?
It did not get pulled in by Earth's gravity. The moon most likely formed when a small planet collided with Earth early in its history, producing a ring of debris around Earth which coalesced to form the moon.

What is the particle size of a electron?
Very small...very small indeed.
Is particles a physical or chemical property?
Particle is not a property; a particle is a form of a material, small size.
