Chapter 6: Problem 2

Fill in the blanks. When two bodies 'A' and 'B' are rubbed, they acquire charge by friction. If the charge on ' \(\mathrm{A}\) ' is positive, then the charge on ' \(\mathrm{B}\) ' is ____.

Short Answer

Answer: Negative

Step by step solution

Understanding charges by friction

When two bodies are rubbed together, they exchange charges. As a result, one body will gain a positive charge while the other will gain an equal amount of negative charge. This phenomenon is due to the transfer of electrons from one body to another.

Determine the charge on body B

Since body A gains a positive charge, it means that it lost some of its electrons to body B during the rubbing process. As body B gained these electrons, it will acquire a negative charge as electrons have a negative charge.

Fill in the blank

As we found out that the charge on body B is negative when the charge on body A is positive, we can fill in the blank as follows: "When two bodies 'A' and 'B' are rubbed, they acquire charge by friction. If the charge on 'A' is positive, then the charge on 'B' is negative."
