If an object made of substance A is rubbed with an object made of substance B, then A becomes positively charged and B becomes negatively charged. If however, an object made of substance C, then A becomes negatively charged, What will happen if an object made of substance B is rubbed against an object made of substance C?
(a) B becomes positively charged and C becomes positively
(b) B becomes positively charged and C becomes negatively charged.
(c ) B becones negatively charged and C becomes positively charged.
(d) B becomes negatively charged and C becomes negatively charged.

Explanation

To solve the problem, we need to analyze the charging behavior of the substances involved when rubbed together. Let's break it down step by step.

### Step 1: Understand the charging behavior of substances A and B
When substance A is rubbed with substance B:
- A becomes positively charged.
- B becomes negatively charged.

This indicates that electrons are transferred from A to B, meaning that A has a stronger affinity for electrons compared to B.
