Question
Suppose an object has a charge of 1 C and gains $6.88 \times 10^{18}$ electrons.
1. What will be the net charge of the object?
2. If the object has gained electrons from a neutral object, what will be the charge on the neutral object?
3. Find and explain the relationship between the total charges of the two objects before and after the transfer.
4. When a third object is brought in contact with the first object (after it gains the electrons), the resulting charge on the third object is 0.4 What was its initial charge?
1. $-0.1 \textrm{ C}$
2. $1.1 \textrm{ C}$
3. The total charge is always $1 \textrm{ C}$, demonstrating the law of conservation of charge.
4. $0.9 \textrm{ C}$
