Assertion: If two long wires, hanging freely are connected to a battery in series, they come closer to each other.
Reason: Force of attraction acts between the two wires carrying currents.

Options

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

Explanation

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

### Step 1: Understand the Assertion
The assertion states that if two long wires, hanging freely, are connected to a battery in series, they come closer to each other.

### Step 2: Analyze the Current Flow
When two wires are connected in series to a battery, the same current flows through both wires. If we assume the current flows in the same direction in both wires, we need to determine the magnetic interaction between them.

### Step 3: Apply the Right-Hand Rule
Using the right-hand rule, we can determine the direction of the magnetic field around each wire. For a straight current-carrying wire, the magnetic field lines form concentric circles around the wire.

### Step 4: Determine the Force Between the Wires
When both wires carry current in the same direction, they will experience a magnetic force of attraction. This is because the magnetic field created by one wire will exert a force on the other wire, pulling them closer together.

### Step 5: Evaluate the Reason
The reason states that a force of attraction acts between the two wires carrying currents. This is true only if the currents in both wires are in the same direction. If the currents were in opposite directions, the wires would repel each other.

### Step 6: Conclusion
In this case, the assertion is true (the wires come closer together if currents are in the same direction), but the reason is not universally true as it depends on the direction of the current. Therefore, the assertion is true, but the reason is false.

### Final Answer
- Assertion: True
- Reason: False
