The correct Answer is:
To determine the type of charge that accumulates on rubber when it is rubbed with glass, we can follow these steps: ### Step 1: Understand the Materials - Identify the two materials involved: rubber and glass. - Recognize that both materials have different affinities for electrons. **Hint:** Consider the properties of rubber and glass in terms of electron affinity. ### Step 2: Friction and Charge Transfer - When rubber is rubbed against glass, friction generates heat. - This heat affects the electrons in both materials. **Hint:** Think about how heat can influence the movement of electrons in materials. ### Step 3: Electron Movement - The electrons in glass are more loosely bound compared to those in rubber. - As a result, when rubbed, some electrons from the glass can transfer to the rubber. **Hint:** Remember that the material with loosely bound electrons tends to lose them when in contact with a material that holds electrons more tightly. ### Step 4: Resulting Charges - After rubbing, the rubber gains extra electrons, which gives it a negative charge. - Conversely, the glass rod loses some electrons, resulting in a positive charge due to a deficiency of electrons. **Hint:** Consider the concept of charge conservation and how the loss of electrons from one material affects its charge. ### Step 5: Conclusion - Therefore, the charge accumulated on the rubber after rubbing it with glass is negative. **Final Answer:** The charge accumulated on the rubber is negative.
