200n because it's 2×5=10so maybe try solving the problem like that ok does that help
The correct answer is: They possess high concentrations of free electrons
The main characteristic of good conductors such as metals is the presence of movable electrically charged particles, or electrons. So, when an electric current is applied to a metal, the electrons will move and allow electricity to pass through them. Materials opposite of metals, with low electron mobility are not good conductors, instead they are called insulators.
Answer:
Explanation:
From the question we are told that:
Charges:
Distance 
Generally the equation for Force is mathematically given by
Therefore
