Electric Force

The document discusses the forces between charged particles, noting that forces are equal and opposite, with specific values provided for different scenarios. It explains how changes in charge and distance affect the strength of the electric force, emphasizing that electric forces are significantly stronger than gravitational forces. Additionally, it describes the attraction between opposite charges and how this interaction causes electrons to orbit protons, akin to planetary orbits around the sun.

i The force between the charges is


equal and opposite.The same
force of 72 N on each other.
It's the same as part b so it’s 72
N

now
F 9N

Same as part b so the force is 9 N.

on
F 2.7 10 N
Same as part b so the force is 2.7

If they are attracted to each other, they have opposite
signs.

Doubling q^1 doubles the force, so the new force is twice


as much.

Doubling q^2 also doubles the force, so the new force is


twice as much.

Tripling q^1 triples the force, so the new force is three


times as much.

Doubling the distance makes the force four times weaker.

Tripling the distance makes the force nine times weaker.

As the charges move closer, the distance decreases, so the


force increases.

Electric forces are much stronger than gravitational


forces.In tiny particles, electric forces are noticeable and
dominate.

Attractive, because they have opposite charges.

The force on the proton is the same as on the electron.So


it's the same as the answer in b.

The electric force between the proton and electron pulls the
electron toward the proton, causing it to orbit in a curved
path. This is similar to how gravity keeps planets in orbit
around the sun.
