A work of 30 joules is done is transferring 5 millicoulombs of charge from a point B to a point A in an electric Held. The potential difference between B and A is
Answer Details
The work done (W) in transferring charge (q) between two points in an electric field is given by the formula:
W = qV
Where V is the potential difference between the two points.
In this question, the work done is 30 J and the charge transferred is 5 mC (or 5 x 10^-3 C).
Therefore, we can rearrange the formula to find the potential difference:
V = W/q = 30 J / 5 x 10^-3 C = 6,000 V
So the potential difference between points B and A is 6,000 volts.
Therefore, the correct option is:
- 6.0 x 10^3 V
