Question

Compare the pair of two charged objects, one has 2 positives and 1 negative and one has 3 positives and 3 negatives?

1) The first object has a net charge of -1 and the second object has a net charge of 0
2) The first object has a net charge of -1 and the second object has a net charge of -3
3) The first object has a net charge of 1 and the second object has a net charge of 0
4) The first object has a net charge of 1 and the second object has a net charge of -3

Answer 1

The first object with 2 positives and 1 negative has a net charge of +1, and the second object with 3 positives and 3 negatives has a net charge of 0, making it electrically neutral.

Step-by-step explanation:

When comparing the net charge of two charged objects, we simply have to count the number of positive and negative charges and find the difference. For the first object with 2 positive charges and 1 negative charge, we have (2 - 1) which results in a net charge of +1, meaning the object is positively charged. In the case of the second object with 3 positive charges and 3 negative charges, they cancel each other out (3 - 3), leading to a net charge of 0, indicating that the object is electrically neutral. Therefore, the correct comparison is: The first object has a net charge of 1 and the second object has a net charge of 0.

Answer 2

The first object with 2 positive and 1 negative charges has a net charge of +1, making it positively charged. The second object with 3 positive and 3 negative charges has a net charge of 0, making it electrically neutral.

Step-by-step explanation:

When comparing the net charge of two objects, we have to count the total number of positive charges and subtract the number of negative charges. For the first object with 2 positives and 1 negative, the net charge is: 2 positives + (-1 negative) = +1. Therefore, the first object has a net charge of +1 and is positively charged. The second object with 3 positives and 3 negatives has a net charge of: 3 positives + (-3 negatives) = 0, making it electrically neutral. So, the correct statement is: The first object has a net charge of 1 and the second object has a net charge of 0.
