The combined charge of all the electrons in a dime is hundreds of thousands of coulombs. Because like charges repel, what keeps the dime from exploding? a. The dime has an equal number of protons, with positive charge. b.The dime has more protons than electrons, with positive charge. c. The dime has fewer protons than electrons, with positive charge. d. The dime is polarized, with electrons on one side and protons on the other side.
The combined charge of all the electrons in a dime is hundreds of thousands of coulombs. Because like charges repel, what keeps the dime from exploding?
a. The dime has an equal number of protons, with positive charge.
b.The dime has more protons than electrons, with positive charge.
c. The dime has fewer protons than electrons, with positive charge.
d. The dime is polarized, with electrons on one side and protons on the other side.
Given , dime is a conductor
we know for a conductor polarization is zero , Electric field inside the surface is zero , and the potential inside is constant . hence all the charges lie on the surface.Therefore option d) is incorrect
Hence the dime has an equal no of protons , with positive charge so that the electric field inside the conductor is zero,to maintain charge inequality
Since , now dime has two types of charges i.e positive and negative and we know opposite charges attract each other . This will keeps the dime from exploding.
Hence option a) is the right answer
With unequal no of protons or electrons , the electric field inside a conductor is not zero .
Hence option b) and c) are wrong
