Assertion : The weight of an object changes from place to place but not mass.
Reason : The weight of the object is independent of the value of g.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both 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 assertion is false but reason is true.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided:

### Step 1: Understand the Assertion
The assertion states: "The weight of an object changes from place to place but not mass."
- **Weight** is defined as the force exerted by gravity on an object, which can be calculated using the formula:
\[ \text{Weight} (W) = \text{mass} (m) \times \text{acceleration due to gravity} (g) \]
- **Mass** is a measure of the amount of matter in an object and remains constant regardless of location.

### Step 2: Understand the Reason
The reason states: "The weight of the object is independent of the value of g."
- This statement is incorrect because weight is directly proportional to the acceleration due to gravity (g). If g changes, the weight will also change.

### Step 3: Analyze the Relationship
- Since weight depends on both mass and the value of g, if g changes (which it does depending on location), the weight will also change.
- Mass, however, remains constant regardless of location.

### Step 4: Determine the Truth of Assertion and Reason
- The assertion is **true**: Weight changes with location, but mass does not.
- The reason is **false**: Weight is dependent on the value of g.

### Step 5: Choose the Correct Option
Based on the analysis:
- The correct option is: **Assertion is true and reason is false.**

### Final Answer
The answer to the question is: **Option 3: Assertion is true and Reason is false.**
