A glass rod is rubbed with a silk cloth and inflated rubber balloon is rubbed with a woollen cloth.
Now , out of glass rod, silk cloth, rubber balloon and woollen cloth :
which two objects acquire positive charge ?

Explanation

To determine which two objects acquire a positive charge when a glass rod is rubbed with a silk cloth and an inflated rubber balloon is rubbed with a woolen cloth, we can follow these steps:

### Step 1: Understand the Charging Process
When two different materials are rubbed together, electrons can transfer from one material to another. The material that loses electrons becomes positively charged, while the material that gains electrons becomes negatively charged.

### Step 2: Analyze the First Pair (Glass Rod and Silk Cloth)
- **Glass Rod and Silk Cloth**: When a glass rod is rubbed with a silk cloth, electrons move from the glass rod to the silk cloth.
- **Result**: The glass rod loses electrons and becomes positively charged, while the silk cloth gains those electrons and becomes negatively charged.
