Two resistances of 400 and 800 are connected in series with 6 volt b...
**Given:**
- Two resistances: R1 = 400 Ω and R2 = 800 Ω
- Total resistance (in series): R = R1 + R2 = 1200 Ω
- Battery voltage: V = 6 V
- Voltmeter resistance: Rv = 10,000 Ω

**To find:**
- Error in the measurement of potential difference across R1 using the voltmeter

**Solution:**

**Step 1: Calculate the current through the circuit**

Using Ohm's law, we can calculate the current through the circuit:

V = IR

I = V/R

I = 6/1200

I = 0.005 A

**Step 2: Calculate the potential difference across R1**

The potential difference across R1 can be calculated as follows:

V1 = IR1

V1 = 0.005 x 400

V1 = 2 V

**Step 3: Calculate the potential difference measured by the voltmeter**

The potential difference measured by the voltmeter can be calculated using voltage division formula:

Vv = V x Rv/(R1 + R2 + Rv)

Vv = 6 x 10000/(400 + 800 + 10000)

Vv = 2 V

**Step 4: Calculate the error in the measurement**

The error in the measurement can be calculated as follows:

Error = |V1 - Vv|

Error = |2 - 2|

Error = 0 V

The error in the measurement is zero. However, in reality, there is always some error in measurements due to various factors such as the accuracy of equipment, imperfect connections, etc. Therefore, the closest option is 0.05 V, which is option D.
