What can we conclude from the attractive nature of the force between a positively charged rod and an object?
1. The object has no net charge.
2. Cannot be determined.
3. The object does not have an appreciable negative charge.
4. The object does not have an appreciable positive charge.
5. The object has an appreciable positive charge.
6. The object has an appreciable negative charge.
I answered this already, when you posted it without all the choices
To determine the correct conclusion from the attractive nature of the force between a positively charged rod and an object, we need to consider the principle of electrical charge and interactions.
When a positively charged rod attracts an object, it suggests that there is an attractive force between them. This can happen when opposite charges are attracted to each other. Based on this information, we can make the following conclusions:
1. The object has no net charge: This conclusion is not necessarily correct, as the object could contain both positive and negative charges, but the attractive force indicates that there is an attractive interaction between the positive charge on the rod and the charges present in the object.
2. Cannot be determined: While it's true that we may not have enough information to conclude with certainty, we can analyze the situation further to make an educated judgment.
3. The object does not have an appreciable negative charge: This conclusion could be correct since the attractive force between the positive rod and the object suggests that there is no strong repulsive force due to an excess negative charge on the object.
4. The object does not have an appreciable positive charge: This conclusion is not correct since the attractive force indicates the presence of charges in the object that are attracted to the positive charge on the rod.
5. The object has an appreciable positive charge: This conclusion is possible because the attractive force indicates that there are positive charges present in the object that are attracted to the positive charge on the rod.
6. The object has an appreciable negative charge: This conclusion is also possible if the object contains negative charges that are attracted to the positive charge on the rod.
In summary, the most accurate conclusion from the attractive nature of the force between a positively charged rod and an object is that the object has either an appreciable positive charge or an appreciable negative charge.
