Question: If the electric potential at a point is 10 V and the electric field is uniform, what is the work done in moving a charge of 2 C from that point to a point where the potential is 0 V?

Options:

20 J
10 J
5 J
0 J

Correct Answer: 20 J

Solution:

Work done W = q(V1 - V2) = 2 C (10 V - 0 V) = 20 J.

If the electric potential at a point is 10 V and the electric field is uniform, what is the work done in moving a charge of 2 C from that point to a point where the potential is 0 V?

Correct Answer: 20 J

Step 1: Identify the initial electric potential (V1) at the starting point, which is 10 V.
Step 2: Identify the final electric potential (V2) at the destination point, which is 0 V.
Step 3: Determine the charge (q) being moved, which is 2 C.
Step 4: Use the formula for work done (W) in moving a charge in an electric field: W = q(V1 - V2).
Step 5: Substitute the values into the formula: W = 2 C (10 V - 0 V).
Step 6: Calculate the difference in potential: 10 V - 0 V = 10 V.
Step 7: Multiply the charge by the potential difference: W = 2 C * 10 V = 20 J.
