1)When two bodies are charged, the total charge before and after charging remains the same because of:
A)quantization of charges
B)conservation of charges
C)law of induction
D)coulomb's law
I got C but im not sure. I couldn't find anything to state otherwise.
2)When a conducting sphere is charged positively, initially the charge is deposited on the left side. However, due to the sphere's conducting nature, the charge spreads uniformly throughout the surface of the sphere. Charge is uniformly distributed because:
A)charged atoms at the location of charge distribute throughout the surface
B)excess protons move from the location of charge to rest
C)excess electrons within the sphere move toward excess protons
D)excess charge within the sphere moves out into the ground from the surface
I got A
1) is B, unless charge is added or removed from somewhere else. I assume that one body is used to charge the other by rubbing
2) A is the closest to being correct. Positively charged areas will be regions deprived of electrons. The charged atoms don't actually move, but available free electrons will redistribute themselves so that positively charged atoms are uniformally distributed.
1) The correct answer is B) conservation of charges. According to the law of conservation of charge, the total charge in a system remains constant. This means that the total charge before and after charging must be the same.
2) The correct answer is C) excess electrons within the sphere move toward excess protons. When a conducting sphere is charged positively, excess electrons are deposited on one side of the sphere. However, due to the conducting nature of the sphere, the excess electrons will distribute themselves evenly throughout the surface of the sphere. This occurs because like charges repel each other, causing the excess electrons to move away from each other and towards the excess protons, which are spread out on the opposite side of the sphere. As a result, the charge becomes uniformly distributed on the surface of the sphere.
1) The correct answer for the first question is B) conservation of charges. To explain why, we need to understand the concept of charge conservation. According to the law of conservation of charges, electric charge cannot be created or destroyed, only transferred or redistributed. So, when two bodies are charged, the total charge before and after charging remains the same because the charges are simply being redistributed between the bodies. Some charge is transferred from one body to the other, but the total charge in the system remains constant.
2) The correct answer for the second question is C) excess electrons within the sphere move toward excess protons. When a conducting sphere is charged positively, initially the excess charge is deposited on a specific location on the sphere. However, due to the conductive nature of the sphere, the excess charge spreads uniformly throughout the surface. This spreading occurs because like charges repel each other, causing the excess electrons within the sphere to move away from each other and distribute themselves uniformly across the surface of the sphere. This equal distribution of charge results in a uniform charge distribution on the surface of the sphere.
