Two uncharged bodies when rubbed against each other get charged. This is known as

Options

A. charging by conduction
B. charging by friction
C. charging by induction
D. none of the above

Answer

To solve the question, "Two uncharged bodies when rubbed against each other get charged. This is known as," we will follow these steps:

### Step 1: Understand the Context
We start with two uncharged bodies. When they are rubbed against each other, they undergo a process that results in both bodies acquiring an electric charge.

**Hint:** Consider what happens at the atomic level when two materials come into contact and are then separated.

### Step 2: Identify the Mechanism
When the two bodies are rubbed together, free electrons from one body may transfer to the other body. This transfer occurs due to friction between the surfaces of the two bodies.

**Hint:** Think about what happens to the electrons when two materials are in contact and then moved apart.

### Step 3: Determine the Charge of Each Body
As a result of the transfer of electrons:
- The body that loses electrons becomes positively charged (due to a deficit of electrons).
- The body that gains electrons becomes negatively charged (due to an excess of electrons).

**Hint:** Remember that losing electrons results in a positive charge, while gaining electrons results in a negative charge.

### Step 4: Name the Process
The process by which two uncharged bodies become charged when rubbed against each other is known as "charging by friction."

**Hint:** Recall the terminology used in electrostatics for processes that involve physical contact and movement.

### Final Answer
The process is known as **charging by friction**.
