A glass rod, a piece of silk, and a piece of cat's fur are all initially uncharged. First, the silk and glass are rubbed together. Next, the glass and fur are rubbed together. Afterward, you determine that the silk has a charge of - 11·nC and the fur has a charge of + 10·nC. What charge, if any, does the glass have?

Jaxson Hodge · Answer 1

1 nC

Explanation:

As initially, the silk and glass rod is rubbed and the silk has a charge of - 11 nC so, the glass has a charge of + 11 nC.

Now glass is rubbed with fur, the fur has a charge of + 10 nC so the glass has a charge of - 10 nC.

So the total charge on he glass rod = + 11 nC - 10 nC = 1 nC.

Thus, the glass rod has a charge of 1 nC.
