I was once given some balloons by the local shop. When I tried to do electrostatics experiments with them they didn't work.
Use quizzes to practise application of theory.

The diagram shows 4 arrangements of 8 units of charge
In which case is the force between the charges greatest
The force is proportional to the product of charge
The diagram shows 4 arrangements of charges
In which case is the force smallest
In C the left sphere has no net charge so the force is zero
A carbon atom has 6 protons and 6 electrons.
The charge of a carbon atom is
electrons are negative and protons positive so net charge is 0
A neutral oxygen atom contains 8 protons, 8 electrons and 8 neutrons
What is the charge of a neutron?
The charges are already balanced so the neutrons must be neutral (hence the name)
A proton is made of 2 up quarks and 1 down quark.
The charge of an up quark is +2/3 e, what is the charge of a down quark?
proton charge is 1 e
2/3 + 2/3 - 1/3 = 1
A, B and C are three plastic rods, A is positively charged.
A attracts B and B attracts C, what charge is C
B is - so C must be +
The diagram represents 2 charges
What is true about the forces on each
Newtons 3rd law: If A pushes B, B will push A with an equal and opposite force
