What are the properties of charge?
Quantization of Charge
Charge is always associated with mass
Conservation of charge
Invariance of charge
This property of charge states that:
electric charges can only have discrete/integer values
Quantization of Charge
This property of charge states that:
A mass cannot exist without charge
Charge is always associated with mass
True or False:
Particles such as photons or neutrinos have mass and have charge
FALSE (they do not have mass and can never have a charge)
True or False:
The higher the electrons, the heavier the object
TRUE
The ____ the protons, the lighter the object
The HIGHER the protons, the lighter the object
This property of charge states that:
charge is conserved in an isolated system
Conservation of Charge
