Metal is a conductor, so the charges are free to move wherever they want inside it. They will rearrange themselves to cancel out any field inside the sphere. So at equilibrium the electric field inside a conductor is zeroIron_Man_123 said:The electric field inside an uncharged metal sphere is initially zero.
If the sphere is the positively charged, the field at the center of the sphere will be...?
No it doesn't matter, The same thing will happen producing a zero electric field inside the hollow sphereIron_Man_123 said:Does the answer change if the sphere is hollow?
Electrical charge is a fundamental physical property of matter that causes particles to experience electromagnetic interactions. It is a measure of the amount of electric energy contained within a material or object.
The unit of electrical charge is the coulomb (C), named after French physicist Charles-Augustin de Coulomb. One coulomb is equivalent to the charge of 6.241509 x 10^18 electrons.
Positive charge is caused by an excess of protons, while negative charge is caused by an excess of electrons. Like charges repel each other, while opposite charges attract each other.
Electrical charge is typically measured using a device called an electrometer, which can detect the presence and magnitude of electric charge. It can also be measured indirectly by observing the effects of electric charge on other objects.
Electric charge and electric fields are closely related. Electric charges create electric fields, which can exert a force on other charges. The strength of an electric field is directly proportional to the magnitude of the charge creating it.
