Questions & Step-by-Step Solutions

What is the potential difference between two points A and B in an electric field if the work done in moving a charge of +2C from A to B is 10J?
  • Step 1: Understand that potential difference (V) is calculated using the formula V = W/Q, where W is the work done and Q is the charge moved.
  • Step 2: Identify the values given in the question: Work done (W) is 10 Joules and the charge (Q) is +2 Coulombs.
  • Step 3: Substitute the values into the formula: V = 10 J / 2 C.
  • Step 4: Perform the division: 10 J divided by 2 C equals 5 V.
  • Step 5: Conclude that the potential difference between points A and B is 5 Volts.
