What is the potential difference between two points of the field, if, when moving between them

What is the potential difference between two points of the field, if, when moving between them, a charge of 0.012 C. the field did work 0.36?

q = 0.012 Cl.

A = 0.36 J.

φ2 – φ1 -?

The mechanical work of the electric field A on the movement of an electric charge of q value from a point with a potential φ1 to a point with a potential φ2 is determined by the formula: A = q * (φ2 – φ1).

The potential difference φ2 – φ1 between the points of the electric field is called the voltage U.

φ2 – φ1 = A / q.

φ2 – φ1 = 0.36 J / 0.012 C = 30 V.

Answer: the potential difference between the points of the field between which the charge moves is φ2 – φ1 = 30 V.
