When Rani ran a comb through her hair vigorously and brought it close to small bits of paper, she found that the bits of paper were attracted to the comb. If Rani's hair got negatively charged when she ran the comb through it, what type of charge must have been induced on the bits of paper?

Explanation

To solve the question, we need to understand the concept of electric charges and how they interact with each other.

### Step-by-Step Solution:

1. **Understanding Charge Induction**: When Rani ran the comb through her hair, her hair became negatively charged. This means that the comb also acquired a negative charge due to the transfer of electrons from her hair to the comb.

2. **Behavior of Charges**: According to the principles of electrostatics, like charges repel each other while opposite charges attract. Since the comb is negatively charged, it will repel any other negatively charged objects and attract positively charged objects.
