In experiments involving a pithball electroscope, what causes the pithball to move? I believe the answer is B
A. The pith material always holds a natural positive charge, and it is attracted to other charged objects.
B. Electrons jump onto or off the neutral ball when a charged object comes close to it, causing it to become charged.
C. As soon as an object approaches the pithball there is an immediate repulsion.
D. The pithball does not become charged but it gets caught up between two other charged objects.
B
yes the answer is B. Electrons become charged when a charged object comes close to it, causing it to become charged.The movement is moved.
I apologize for the mistake in my previous response. As an AI language model, I will always provide accurate information to the best of my ability. However, I do not have the ability to verify the correctness of the information given to me. In experiments involving a pithball electroscope, the pithball moves due to the transfer of charge through the process known as electrostatic induction. When a charged object is brought close to the neutral pithball, the charges in the pithball are redistributed, causing it to become charged and move. This redistribution of charges is caused by the repulsion or attraction of charges between the objects involved.
To determine the correct answer, let's analyze each option:
A. The pith material always holds a natural positive charge, and it is attracted to other charged objects.
This statement suggests that the pithball already has a positive charge and is attracted to other charged objects. However, in the context of the experiment, the pithball starts off neutral and becomes charged due to an external influence.
B. Electrons jump onto or off the neutral ball when a charged object comes close to it, causing it to become charged.
This answer accurately explains what happens in experiments involving a pithball electroscope. When a charged object approaches the neutral pithball, electrons can be transferred onto or off the pithball, leading it to become charged and move accordingly. This is known as the process of charge induction.
C. As soon as an object approaches the pithball, there is an immediate repulsion.
This statement contradicts the observation that the pithball can become attracted or repelled depending on the type of charge induced onto it. The pithball's behavior is not solely based on repulsion.
D. The pithball does not become charged but gets caught up between two other charged objects.
This answer suggests that the pithball does not become charged but rather gets caught between two other charged objects. However, this explanation does not align with the concept of charge induction and the movement of the pithball in response to the presence of charged objects.
Based on the analysis, the correct answer is B. Electrons jump onto or off the neutral ball when a charged object comes close to it, causing it to become charged.
