When an object gets negetively charged by the process of friction, then :

Options

A. the object loses some electrons
B. the object loses some protons
C. the object gains some electrons
D. the object gains some protons

Answer

To solve the question about what happens when an object gets negatively charged by the process of friction, we can follow these steps:

### Step 1: Understand Charging by Friction
When two objects are rubbed together, electrons can be transferred from one object to another. This process is known as charging by friction.

**Hint:** Remember that friction involves contact between two surfaces, which can lead to the movement of charged particles.

### Step 2: Identify the Charge Carriers
Electrons are the charge carriers that can move between objects. They carry a negative charge, while protons, which are found in the nucleus of atoms, do not move during this process.

**Hint:** Focus on the fact that electrons are mobile and can be transferred, while protons remain fixed in the atomic structure.

### Step 3: Determine the Result of Electron Transfer
When an object gains electrons, it accumulates a negative charge. Therefore, if an object becomes negatively charged, it must have gained electrons from another object.

**Hint:** Think about what happens to the overall charge of an object when it gains negative particles (electrons).

### Step 4: Analyze the Options Given
- Option 1: The object loses some electrons (Incorrect, as it would become positively charged).
- Option 2: The object loses some protons (Incorrect, as protons do not move).
- Option 3: The object gains some electrons (Correct, as this leads to a negative charge).
- Option 4: The object gains some protons (Incorrect, as protons do not move).

**Hint:** Eliminate options that contradict the fundamental principles of charge transfer.

### Step 5: Conclusion
The correct answer is that when an object gets negatively charged by the process of friction, it gains some electrons.

**Final Answer:** Option 3: The object gains some electrons.
