Assertion(A) : The earth revolves around the sun an elliptical orbit
Reasoning(R) : The sun alwaye attracts the earth with the same force

Options

A. both Assertion and Reason are both are both wrong
B. Assertion is right, Reason is wrong
C. both Assertion and Reason are correct and Reason explains Assertion
D. both Assertion and Reason are correct, but Reason does not explain Assertion

Answer

To solve the question, we need to evaluate the assertion and reasoning provided:

**Assertion (A):** The earth revolves around the sun in an elliptical orbit.
**Reasoning (R):** The sun always attracts the earth with the same force.

### Step-by-Step Solution:

1. **Understanding the Assertion (A):**
- According to Kepler's laws of planetary motion, specifically the first law, planets (including Earth) move in elliptical orbits with the Sun at one of the foci.
- This statement is true.

2. **Understanding the Reasoning (R):**
- The gravitational force between two bodies (such as the Earth and the Sun) is given by Newton's law of gravitation:
\[ F = \frac{G \cdot m_1 \cdot m_2}{r^2} \]
where \( F \) is the gravitational force, \( G \) is the gravitational constant, \( m_1 \) and \( m_2 \) are the masses of the two bodies, and \( r \) is the distance between their centers.
- As the Earth moves in its elliptical orbit, the distance \( r \) between the Earth and the Sun changes. Therefore, the gravitational force acting on the Earth by the Sun also changes as the distance changes.
- This means that the statement "the sun always attracts the earth with the same force" is incorrect.

3. **Conclusion:**
- Since the assertion is true and the reasoning is false, we conclude that the correct answer is that the assertion is true, but the reasoning is false.

### Final Answer:
- Assertion (A) is true.
- Reasoning (R) is false.
- Therefore, the correct option is that Assertion is true and Reasoning is false.
