Question: If the electric potential at point A is 10 V and at point B is 5 V, what is the work done by the electric field in moving a charge from A to B?

Options:

5 J
10 J
15 J
0 J

Correct Answer: 5 J

Solution:

The work done (W) by the electric field is given by W = q(V_A - V_B). For a unit charge, W = 10 V - 5 V = 5 J.

If the electric potential at point A is 10 V and at point B is 5 V, what is the work done by the electric field in moving a charge from A to B?

Correct Answer: 5 J

Step 1: Identify the electric potential at point A, which is given as 10 V.
Step 2: Identify the electric potential at point B, which is given as 5 V.
Step 3: Calculate the difference in electric potential between points A and B. This is done by subtracting the potential at B from the potential at A: 10 V - 5 V.
Step 4: The result of the subtraction is 5 V. This value represents the change in electric potential when moving from A to B.
Step 5: The work done (W) by the electric field in moving a unit charge (1 Coulomb) from A to B is equal to the change in electric potential. Therefore, W = 5 V.
Step 6: Since 1 Volt is equivalent to 1 Joule per Coulomb, the work done is 5 Joules.
