What else can I help you with?
When positive and negative attract which initiate the attraction?
Because the charges are equal in magnitude, the attraction is simultaneous.
Why like charges repel and unlike charges attract each other?
The reason why some charges repel while unlike charges attract comes down to polarity. According to Newton, with every action there is an equal and opposite reaction. The reason comes down the the amount of protons and electrons in each atom. Equal amounts produce a repelling action where as charges with unequal protons and elections will cause the atoms to attract.
What is a opposite charged?
Opposite charges refer to charges that are different in sign but equal in magnitude. For example, positive and negative charges are considered opposite charges in the context of electricity. Opposite charges attract each other according to the law of electrostatics.
What is a good comparison of the charges of an electron and the charges of a proton?
They are equal in magnitude but opposite in charge.
What particles have negative electric charges equal to the positive charges of the protons?
The electrons; their negativity cancels out the protons' positivity so the atom is electrically neutral.
Two equal charges exert equal forces on each other What if one charge has twice the magnitude of the other?
Whatever be the magnitude of charge, two charges will always exert equal force on each other. As force depends on the product of magnitude of charges, it will increase if magnitude is doubled but will remain same for both the charges.
What do electrons have that protons always have in equal magnitude?
Electrons have negative charge and protons have positive charge. These charges always have equal magnitude but opposite signs in an atom, maintaining electrical neutrality.
What condition must be met for the electric field between two charges to be zero?
The condition for the electric field between two charges to be zero is when the charges are equal in magnitude and opposite in sign.
What is the condition for the electric potential to be zero between two opposite charges?
The condition for the electric potential to be zero between two opposite charges is when the charges are equal in magnitude and opposite in sign.
What is an attraction between a positive ion and a negative ion?
they will attract if they have equal and opposite charges, such as Na and Cl
How positive and negative attract?
Think about it in science. If you had any atom with only positive charges or just negative charges it is an unstable atom, therfore you can't make anything out of it. They attract like puzzle pieces. To stabalize an object you need an equal amount of positive and negative charges.
What is the separation between two equal charges if force between them is equal two the weight of a 50 kg person?
That's going to depend on the magnitude of the charges. You've said that they're equal, and that's appreciated although unnecessary. But we still need a number.
