A point charge q = 10 nC, located at a certain point of the electrostatic field

A point charge q = 10 nC, located at a certain point of the electrostatic field, has a potential energy of W = 10 mJ. Determine the potential φ of this point of the field.

To calculate the value of the potential at the indicated point of the field, we will use the formula: φ = Wп / q.

Variable values: Wp – potential charge energy (Wp = 10 μJ = 10 * 10 ^ -6 J); q is the amount of charge (q = 10 nC = 10 * 10 ^ -9 C).

Let’s perform the calculation: φ = Wp / q = 10 * 10 ^ -6 / (10 * 10 ^ -9) = 1 * 103 V = 1 kV.

Answer: The potential at the indicated point of the field is 1 kV.
