Electrostatic Force

Three subatomic particles

Electron, neutron, proton

Electrons and Protons are different from neutrons because

Electrons and protons are charged while neutrons are neutral; locations are different (mostly in nucleus)

Electrons v Protons

Electrons negative, Protons positive; electrons in electron cloud outside nucleus with less mass; Protons in nucleus with more mass

Which charges repel?

Like charges

Which charges attract?

Opposites

Electric field for proton

Arrows pointing away

Electron field for electron

arrows pointing to it

Electric field strongest charge

C, the most arrows

Electric field weakest charge

Least field lines, A

What are electric field arrows called?

Field lines

Closer the charged object, the ___ the force of the electric charge

stronger

When rubbing wool on a balloon…

the electrons are transferred from the wool to the balloon, making the wool positively charged and the balloon negative. they are therefore attracted to each other because opposite charges attract.

Electric field lines of proton and electron close by

field lines point away from proton towards electron

Electrostatic force is ___ proportional to distance

inversely (inverse square law applies)

Electrostatic force is ___ proportional to q

directly
