Acharge q of 7.3 × 1015 coulomb moves from point a to point b in an electric field. if the potential energy of the charge at point a is 3.5 × 10-12 joules and that at point b is 1.3 × 10-12 joules, what is the potential difference between point a and b?

The potential difference between point A and B is .

Explanation:

Given that,

Charge,

Potential energy at point A,

Potential energy at point B,

To find,

The potential difference between point A and B or

Solve,

We know that the relationship between the potential difference and the potential energy is given by :

Where

is the difference in potential energy between A and B

is the potential difference between point A and B

Therefore, the potential difference between point A and B is .
