Calculation of Potential Difference

To find the potential difference between two points on the same field line, we can use the formula:

V = E * d

Where: - V is the potential difference (in volts) - E is the electric field strength (in N/C or V/m) - d is the distance between the two points (in meters)

In this case, the electric field strength is given as 14 MV/m (megavolts per meter), and the distance between the points is 5 cm (0.05 m). We need to convert the electric field strength to volts per meter before calculating the potential difference.

Converting 14 MV/m to V/m: 1 MV = 1,000,000 V So, 14 MV/m = 14,000,000 V/m

Now we can calculate the potential difference:

V = (14,000,000 V/m) * (0.05 m)

Calculating the result: V = 700,000 V

To convert the potential difference to kilovolts (kV), we divide the value by 1000:

V(kV) = V / 1000

Calculating the result: V(kV) = 700,000 V / 1000 = 700 kV

Therefore, the potential difference between the two points on the same field line is 700 kV.
