Assertion: Friction depends on the weight of the object
Reason: A heavier object exerts a greater frictional force

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If oth assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

To analyze the given assertion and reason, we can break down the problem step by step.

### Step 1: Understand the Assertion
The assertion states that "Friction depends on the weight of the object."
- **Explanation**: Friction is a force that opposes the motion of an object. It is influenced by the weight of the object because the weight determines the normal force acting on the object. The greater the weight, the greater the normal force, which in turn increases the frictional force.

### Step 2: Understand the Reason
The reason states that "A heavier object exerts a greater frictional force."
- **Explanation**: A heavier object has a greater weight, which leads to a larger normal force. Since frictional force is directly proportional to the normal force, a heavier object will indeed exert a greater frictional force.

### Step 3: Establish the Relationship
Now, we need to establish the relationship between the assertion and the reason.
- **Explanation**: The assertion is true because friction does depend on the weight of the object. The reason is also true because it explains why a heavier object exerts a greater frictional force due to the increased normal force.

### Step 4: Conclusion
Based on the analysis:
- Both the assertion and the reason are true.
- The reason provides a correct explanation for the assertion.

### Final Answer
Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.
