Question: If the electric potential at a point is 200 V and the electric field is uniform, what is the work done in moving a charge of 0.5 C to a point where the potential is 100 V?

Options:

50 J
100 J
200 J
0 J

Correct Answer: 100 J

Solution:

Work done W = q * (V1 - V2) = 0.5 C * (200 V - 100 V) = 50 J.

Questions & Step-by-Step Solutions

If the electric potential at a point is 200 V and the electric field is uniform, what is the work done in moving a charge of 0.5 C to a point where the potential is 100 V?

Step 1: Identify the initial electric potential (V1) which is 200 V.
Step 2: Identify the final electric potential (V2) which is 100 V.
Step 3: Identify the charge (q) which is 0.5 C.
Step 4: Calculate the difference in electric potential (V1 - V2) which is 200 V - 100 V = 100 V.
Step 5: Use the formula for work done (W = q * (V1 - V2)).
Step 6: Substitute the values into the formula: W = 0.5 C * 100 V.
Step 7: Calculate the work done: W = 50 J.
